Stendek - Vol 09 No 31 - March 1978

Magazine Overview

STENDEK, Servicio Informativo C.E.I., Año IX, N° 31, published in March 1978, is a quarterly publication from the Centro de Estudios Interplanetarios (CEI). The issue is directed by Pere Redón, with Maria del Carmen Tamayo as Assistant Editor and Josep Serra Planas as Layout Artist. Illustrations are provided by Salvador Barroso and Germán Montfort. The magazine focuses on UFO phenomena and related research.

Editorial

The editorial reflects on the I Congreso Nacional de Ufología held three months prior. It highlights two irreconcilable approaches to ufology: the scientific and rigorous field investigation versus the sensationalist and mystical interpretations often promoted by writers and parapsychologists. The editorial emphasizes that experienced researchers are wary of sensationalism and publicity, having seen its excessive frequency. It notes the emergence of 'cosmic prophet' narratives within OVNI phenomenology, which, while not surprising, serve to contrast idealistic conceptions with reality. The congress is seen as reinforcing the union of serious investigators, accentuating their critical spirit, and demonstrating that years of study are yielding interesting, albeit not sensationalist, results. The editorial is signed by Adell, Ares, Ballester, Guasp, Lopez, Ramirez y Barbero, Redon, Salaverria y Tamayo.

Articles and Contents

Argentina: La sorprendente noche de Huaco (The Surprising Night of Huaco) by Dr. Oscar A. Calíndez (Pages 2-9):
This is the lead article, detailing a significant UFO encounter experienced by four witnesses in Huaco, Argentina, on the night of December 11-12, 1972. The witnesses, Hiram José Larcher, Marcelo B. Aballay, Nicasio F. Martino, and Agustín Vignoli, were on an excursion in a remote, mountainous, uranium-rich area. The article describes multiple phenomena observed:

• A Luminous Triangle (Coherent Light): Around 11 PM, a brilliant, inverted triangle of white, mercury-like light was projected onto a rocky mountainside about 200 meters away. The light was sharp, with defined edges, and illuminated the area with astonishing clarity, highlighting natural features. The phenomenon lasted about four minutes and disappeared from the bottom vertex.
• A Spherical Light and Strange Sound Phenomenon: Around 11:30 PM, a spherical light, resembling a car headlight, moved slowly from southeast to northwest over a mountain. It stopped at the southern end of the mountain. Shortly after, a cry of a woman, described as conveying pain and terror, was heard. The light then resumed its movement, not following the winding road but moving in a straight line, suggesting it was not a vehicle. This phenomenon lasted approximately two minutes.
• Dozens of Luminous Spheres: Around 4:55 AM, witnesses were awakened by an intense wave of heat. They observed numerous luminous spheres, described as ovoid, about 4-5 cm in diameter, moving at high speed in a zig-zag pattern close to the ground, almost tracing its contours. There were about 30-40 of these spheres. They moved silently and without emitting any odor. The heat subsided after their departure, but a feeling of heaviness and fatigue persisted for hours.
• A Large Brilliant Sphere: Around 5:00 AM, a large sphere, estimated to be 6-8 meters in diameter, appeared from the south and moved northeast. It was a soft, silver-white color, with a dark nucleus resembling an 'S' and small, pinkish-yellowish bright dots on its surface. Iridescent lights were visible around its periphery. It moved silently at about 30 km/h and disappeared in the direction of Guandacol, La Rioja. This phenomenon was observed for 8 minutes.
• Formation of Three Unidentified Lights: About 20 minutes after the large sphere disappeared, three luminous spheres of decreasing size appeared in a line. The smallest one broke formation, accelerated rapidly, and rejoined the others. They disappeared in the same direction as the large sphere, appearing to be the size of a first-magnitude star.
• Fast Passage of a Luminous Sphere: Three minutes later, a bright sphere moved rapidly and silently across the sky at high altitude from south to north.

The article notes the proximity of uranium mines (Mina de los señores Saso and Gualampi) to the area, which are known for their radioactivity. The witnesses initially considered military maneuvers but dismissed it due to the nature of the phenomena. The article concludes by stating the conviction of the witnesses' sincerity and the reality of the phenomena.

Recurring Themes and Editorial Stance

The recurring themes in this issue are UFO sightings, case studies, and the scientific investigation of anomalous aerial phenomena. The editorial stance is clearly in favor of rigorous, scientific inquiry, distinguishing it from sensationalist and mystical interpretations. The magazine aims to present well-researched cases and theoretical discussions within the field of ufology, promoting critical thinking among its readers and contributors.

This issue of "Ovni" magazine, dated December 1972, focuses on a series of significant UFO sightings that occurred in Argentina and Chile, with a particular emphasis on events in San Juan province, Argentina. The issue also includes a detailed analysis of a UFO landing case in Gallarta.

IV.- Other Witnesses.

A.- In Argentina.

The magazine reports on multiple testimonies from San Juan province on December 12, 1972. At Tamberías, police officers observed a very white, circular object moving at high speed from west to east, emitting iridescent flashes. In Rodeo, a similar object, described as a round cloud, was seen moving towards the capital city. In Rivadavia, residents and hospital staff witnessed a large, round white object with violet reflections moving at surprising speed towards the mountains. Police confirmed the sighting and noted the object was heading towards the Pie de Palo mountains. In Marquesado, near Regiment 22, several people reported seeing a low-flying, clear gray cloud-like object that emitted small, intermittent flashes from its center. Finally, in Trinidad, individuals reported seeing a "rare object" that emitted a certain glow, resembling the moon but distinctly not the moon.

B.- In Chile.

The issue also covers sightings in Chile. On December 11, 1972, near Pollanco in the precordillera of San José de Maipo, students observed a luminous spherical object, pinkish-grey with a darker circumference, moving slowly. The following night, two spheres were observed, one larger and one smaller, crossing the sky. The magazine also mentions reports from La Serena on December 12, 1972, of a luminous phenomenon similar to a bright cloud, and refers to analogous events in Talca and Baños Campanario on December 13, 1972, citing a scientific report that suggested the phenomena might be "ionized gas clouds."

V.- Author's Comments.

The author provides an analysis of the reported phenomena, highlighting several key aspects:

1.- Coherent Light.

A significant technological detail noted is the "coherent light" emitted by some UFOs. The magazine references a catalog of 128 global UFO episodes involving "compact" light emissions and points out the novel aspect of coherent light projection onto a surface, as seen in the Huaco case where the light seemed "stamped" on an area rather than emanating from a visible source. A similar phenomenon was reported in Das Hochfeld, where a geometric figure was projected onto the ground.

2.- Strange Screams.

The report notes the perception of a "heart-rending scream" resembling a woman's voice in the Huaco case. This phenomenon is linked to other UFO cases where witnesses reported strange sounds, sometimes described as animalistic or human-like cries, such as those in Berserk, Indiana, and River Road, Mississippi. The author suggests these "strange noises" might be part of a common cause or phenomenon and recommends revisiting studies on mysterious animals associated with UFOs.

3.- Luminous Spheres.

The small luminous spheres observed in Huaco raise questions about their role in UFO phenomena. These "foo-fighters" or "krauts fireballs" have been a subject of curiosity for decades. The article mentions various interpretations, including "teleprojections" and "plasmoids."

4.- Secondary Effects.

Physical and physiological effects associated with UFO presence are discussed, including strong caloric sensations and marked somnolence reported in the Huaco case. These effects are theorized to be caused by objective physical phenomena or subjective psychological responses from the witnesses. Two theories are presented: one suggesting a force field generated by the UFO, and another proposing the effects are due to microwaves emanating from the craft. A third theory posits self-hypnosis induced by the visual impact of the sighting.

5.- The Great Sphere.

This phenomenon, considered the most important of the Huaco event, is analyzed. The author dismisses the possibility of it being a meteorite due to its prolonged observation time, slow movement, and lack of sound. It is also unlikely to be plasma or a weather balloon due to its size, luminosity, and transparency. The article concludes it is an unknown phenomenon, possibly linked to other luminous events occurring over a six-hour period across Argentina and Chile.

6.- Fast-moving Spheres.

Several spheres were observed moving at high speed, covering a significant distance in a short time. The witnesses themselves dismissed the possibility of these being meteoric phenomena, citing their controlled, horizontal flight, lack of trails, and apparent self-propulsion.

7.- Aquifers and Radioactive Sources.

The article notes the proximity of the sightings to natural features like the Huaco River and three radioactive sources (uranium mines). The trajectories of several phenomena, including the luminous spheres and the great sphere, appear to be directed towards these radioactive areas, suggesting a possible connection.

Gallarta Case Analysis.

The issue also includes an article by Albert Adell of C.E.I. titled "Un campo de aterrizaje de ovnis en Gallarta" (A UFO landing field in Gallarta). This section details a case involving multiple UFO landings in Gallarta, located in the Basque Country of Spain. The author expresses the challenges of analyzing UFO cases due to conflicting data and subjective interpretations. The Gallarta case is presented as having significant "Strangeness - Credibility" indices. The analysis highlights the difficulties in establishing a coherent narrative from the collected testimonies and expresses gratitude to those who contributed to the investigation. The geographical description of Gallarta and its surrounding mining areas is provided, setting the context for the reported events.

VI. Conclusion.

The magazine concludes that the phenomena reported in Huaco represent one of the most scientifically relevant UFO episodes in Argentina due to the variety of unknown manifestations, their extension to neighboring regions, and the quality of the observers. The difficult identification of these phenomena with known manifestations is emphasized.

Recurring Themes and Editorial Stance.

The magazine consistently focuses on detailed, eyewitness accounts of UFO phenomena, often corroborated by multiple witnesses or official reports (e.g., police). There is a strong emphasis on analyzing the physical characteristics of the observed objects, their behavior, and any associated effects on witnesses or the environment. The editorial stance appears to be one of serious investigation into unexplained aerial phenomena, seeking scientific explanations while acknowledging the often unusual and perplexing nature of the events. The recurring theme of potential connections between UFO sightings and geographical features, particularly those related to natural resources like uranium, is a notable aspect of the magazine's approach.

This issue of UFO Reporter, dated from the 1970s, focuses on UFO sightings and related phenomena, featuring detailed witness testimonies and a review of Steven Spielberg's film "Encuentros en la Tercera Fase" (Close Encounters of the Third Kind).

The Witnesses: Juan Sillero Rábade and Family

The central part of the magazine details the experiences of Juan Sillero Rábade, a 49-year-old carpenter from Aguilar de la Frontera, Spain, and his family. Sillero, described as a sober, simple, and extroverted individual with an excellent reputation, reported multiple encounters with UFOs. His wife, Purificación Fernandez Veiga, is described as reclusive and unwilling to discuss the events, leading some investigators to speculate about her motives. The article notes her "huraña" (unsociable) and "huidiza" (elusive) nature, suggesting she may have been afraid.

Sillero's daughter, María, and her husband, José Luis Lozón, an naval engineer, were also witnesses to a significant event a month before the main Type I cases. They observed a luminous red ball descending from the sky, which hovered and then ascended rapidly. This observation, described as "something from another world," was corroborated by Lozón.

The Sightings and Landings

The magazine meticulously recounts four specific landing incidents reported by Juan Sillero:

• First Landing (around February 10th): The incident began with intense barking from dogs, followed by a persistent humming sound. Sillero observed a luminous object descending over a dump site. The object had landing gear and hovered for several minutes before ascending. He described it as "a phenomenon from another world."
• Second Landing (about a week later): Similar to the first, this event also involved dog barking and a humming sound. Sillero observed the UFO again, noting it seemed larger and closer. He reported seeing a "tank-like" device with a chain and antenna emerge from the underside of the craft. This device performed maneuvers below the UFO before the main craft illuminated intensely and ascended.
• Third Landing (March 21st, around midnight): This was the most dramatic encounter. A massive UFO, estimated at 50 meters in diameter, hovered menacingly close to Sillero's house. He described it as being so close he felt he could touch it. He observed figures moving slowly inside the craft, appearing like shadows. The object remained for about 20-25 minutes before departing at tremendous speed.
• Fourth Landing (date not specified, but after the third): Sillero described a UFO with landing gear that repeatedly attempted to land on the dump site, oscillating and re-bouncing as if unsure of the ground's stability. He observed a luminous disc with four legs.

Sillero's descriptions of the UFOs include details about their shape (two plates joined, with a spherical cap), size estimates, and luminosity. He also noted the absence of any animal distress during some of the sightings, which he found unusual, speculating that the UFOs might emit infrasound.

UFOs in Vizcaya

A brief news report from Bilbao, Spain, is included, detailing the discovery of over 80 landing footprints on an esplanade in the mining area of Gallarta, Vizcaya. Witnesses reported seeing UFOs and hearing strange noises and lights emanating from the isolated area. A technical director from a Bilbao shipyard reported seeing a "mushroom-shaped" object ascend rapidly from the area.

Film Review: "Encuentros en la Tercera Fase" (Close Encounters of the Third Kind)

The latter part of the magazine is dedicated to a review of Steven Spielberg's film "Encuentros en la Tercera Fase." The film is lauded as a highly anticipated science fiction masterpiece that taps into a deep human fascination with the unknown. The review highlights the film's scientific advisor, Dr. J. Allen Hynek, and his classification of UFO encounters (EC3 - Close Encounters of the Third Kind), which involves the presence of occupants.

The film is praised for its realism, with the reviewer noting that the depicted events and witness reactions are strikingly similar to documented UFO cases. The review emphasizes that the film's depiction of the "contact" phase is resolved with brilliance and verisimilitude, presenting a plausible scenario for first contact with extraterrestrial beings. The enigmatic occupants of the UFOs are presented without revealing their origin or intentions, leaving room for the viewer's imagination.

Steven Spielberg is quoted as saying the film is to UFOs what "French Connection" is to crime films, emphasizing its gritty realism. The review concludes by stating that the film is likely to serve as an incentive for more exhaustive research into UFOs and visions, potentially making the public realize "that we are not alone."

Recurring Themes and Editorial Stance

The magazine consistently emphasizes the importance of witness testimony and the search for verifiable evidence in UFO research. The detailed accounts of Juan Sillero's experiences, presented with a degree of skepticism and analysis of his personality, highlight the magazine's commitment to documenting these phenomena. The review of "Encuentros en la Tercera Fase" reinforces the idea that realistic portrayals of UFO encounters can legitimize the field and encourage further scientific investigation. The editorial stance appears to be one of open-minded inquiry, seeking to understand UFO phenomena through credible accounts and scientific perspectives, while acknowledging the psychological aspects involved.

This issue of Stendek, dated June 1974, focuses on UFO landing cases and witness testimonies, with a prominent cover story detailing an "ATERRIZAJE EN LOS ALTOS DE GAINCHURIZQUETA EN 1955." The magazine presents detailed accounts, investigations, and analyses of these phenomena.

Case Study: Gainchurizqueta Landing (1955)

The issue revisits a case initially reported in STENDEK issue 28, concerning an event involving J.M.P. on December 6, 1954. The investigation was aided by Juan Pedro Calvo of "San Sebastián, 20 horas," who provided radio time. The article then focuses on a subsequent landing case, dated January 5, 1955, identified as case number 15 in Vicente J. Ballester Olmos' "Estudio de 100 aterrizajes de OVNIs en la Península Ibérica." This case involved Félix Galarraga and Gerardo Irazusta, who witnessed a UFO near a quarry in Gainchurizqueta. The object was described as round, very brilliant, and approximately three meters in diameter. It descended, appeared to touch the ground, and then ascended rapidly. The observation lasted about three to four minutes. Another witness, who had worked in the quarry in the mid-1950s, recalled seeing a brilliant object descend to the quarry's edge and then ascend quickly, noting its color was white, contrary to the press reports which described it as reddish.

Case Study: Mañeru Landing (Navarre, 1976)

This section details a possible landing with a humanoid in Mañeru, Navarre. The case came to light through friends discussing a potential UFO landing in the region. The investigation team, being geographically closer, committed to an on-site inquiry. They received press clippings and written accounts from child witnesses. The case involved five children (Mari Carmen Santesteban, Alfredo Arbeloa, Miguel Martinez, Ma Natividad Salvador, and Javier Lisarri) who, during a school outing on February 18, 1976, witnessed a UFO. The object was described as metallic, with a crystal top and three wheels, and it landed. A tall, stout figure emerged and walked a few meters before re-entering the craft. The children reported finding large footprints (45 cm) later. The article includes verbatim accounts from the children, translated into Spanish, describing their experiences. Mari Carmen Santesteban described the object as similar to a helicopter, metallic with a crystal part, and it landed without noise. Alfredo Arbeloa also described a metallic object with a crystal top and wheels. Mikel Martinez recounted seeing a man emerge from the object. Ma Natividad Salvador described the object as having a red underside and landing after a curve, with a light reflecting from the crystal part that temporarily blinded Javier.

Analysis of the Gallarta Case and Witness Credibility

The magazine also discusses the Gallarta case, applying a "Strangeness-Credibility Test" to evaluate the reliability of witness Juan Sillero. The test assesses various factors, including the witness's profession (carpenter), objectivity, physical and psychological health, moral reputation, and motivation for notoriety. Most factors are rated positively, with the witness's outburst of frustration at being hounded by investigators being highlighted as a positive indicator of sincerity. The test notes that the case involves a single witness for the 'Type I' encounters, which is a negative factor. The article also touches upon the difficulty in precisely dating events, attributing it to the nature of the sightings (nighttime, rural settings) and the emotional impact on witnesses.

Technical and Investigative Details

The issue includes information about technical presentations by various individuals from CEI (Centro de Estudios Interplanetarios) at a National Ufology Congress in Barcelona in December 1977. It also mentions the publication "Stendek" and its limited edition of 250 copies, priced at 300 pesetas. The article emphasizes the importance of detailed investigation and the challenges of gathering accurate information, especially regarding timelines and witness accounts.

Recurring Themes and Editorial Stance

The recurring themes in this issue are UFO landings, witness testimonies, physical trace evidence, and the rigorous investigation of these phenomena. The magazine adopts a stance of careful, yet open-minded inquiry, attempting to apply systematic methods like the 'Strangeness-Credibility Test' to evaluate the reliability of reports. While acknowledging the extraordinary nature of the claims, the editorial approach seems to lean towards validating credible accounts, particularly when supported by multiple witnesses or physical evidence. There is a clear effort to document and analyze cases thoroughly, often referencing previous publications and ongoing investigations within the ufological community.

Title: foto. ovni
Issue: Extra
Date: March 13, 1975
Publisher: G.E.U. (Grupo de Estudios Ufológicos de Sanlúcar la Mayor)
Country: Spain
Language: Spanish

This issue of 'foto. ovni' delves into various UFO sightings and related phenomena, with a strong emphasis on witness testimonies, particularly from children, and photographic evidence. The cover features a silhouette of a humanoid figure and drawings of UFOs, setting the tone for the articles within.

Children's Testimonies and Drawings

The magazine presents accounts from children who witnessed UFOs and a humanoid figure. Mikel describes a tall, thick humanoid in a metal-like suit that came out of a UFO and walked around, leaving footprints. Alfredo corroborates this, noting the suit appeared to be metal and the figure walked normally. Ma NATIVIDAD recounts an encounter with a metallic UFO with a crystal dome and colored lights, described as the size of a helicopter, which approached them with a yellow and red light.

Javier Lisarri, one of the child witnesses, is highlighted for his expressive drawings. The investigation into the children's accounts focused on verifying their written and drawn testimonies. It was discovered that the striking similarity in their drawings of the craft was due to the teacher having the children draw what they saw on the blackboard, with Javier being the one who initially depicted it. The children's accounts were consistent and detailed, leading researchers to believe they had indeed seen something, even if its nature was uncertain.

José Manuel Mora's UFO Photographs

A significant portion of the issue is dedicated to the case of José Manuel Mora Quesada, a 17-year-old from Sanlúcar la Mayor, who claims to have photographed a UFO on March 13, 1975. Mora recounts how he saw an orange-colored object while returning home from his studies. He managed to take several photographs of the object as it approached and hovered near his house. These photographs were later submitted for expert analysis.

The expert analysis, conducted by a team in Madrid, concluded that the photographs were genuine and not a result of trickery. The report noted the amateur nature of the photography, the lack of signs of manipulation, and the limitations of the camera used, which would make double exposures or sophisticated hoaxes difficult. A later analysis of one of the photos revealed an oval object that had not been initially visible, described as appearing to 'take off'. The object's diameter was estimated to be between 30 and 40 meters.

Temporal Anomalies and UFO Encounters

The magazine explores the intriguing phenomenon of temporal distortions associated with UFO encounters. The article "PROBLEMAS TEMPORALES DEL FENOMENO OVNI" by Luís R. Gonzalez discusses cases where time appears to be contracted or dilated for witnesses.

One case from Yuste (December 31, 1968) describes a witness who experienced a time distortion, arriving two hours later than expected without any apparent reason. Another case from Santa Isabel, Argentina (September 27, 1972), involves a worker who encountered a humanoid figure and experienced a loss of time, with his vehicle accelerating on its own.

Further examples include the famous Hill case (September 19, 1961), where the witnesses experienced a loss of consciousness and time contraction. Cases from Spain (Huesca-Monzón and Doñana) and Argentina (Arroyito-Montecristo) are also presented, detailing instances of memory loss or perceived time compression during or after UFO sightings.

The article contrasts these cases with others where time seems to be 'saved' or where a phenomenon of 'mobile paralysis' is observed, as in the Doñana case. The author suggests that these temporal effects, while seemingly extraordinary, are part of the broader UFO phenomenon and should be considered.

Research and Case Studies

The issue also touches upon ongoing research in the field of ufology. The work of Félix Ares de Blas and M.C. Garmendia Goicochea is mentioned, highlighting a scientific study of the 1968-69 UFO wave. This research, published in a volume of over 300 pages, is described as establishing the basis for analytical studies of the phenomenon using data processing systems.

Additionally, the magazine lists several UFO cases by order of appearance, including those from Yuste, Santa Isabel, Washington, the Hill case, Monzón, Montecristo, Australia, Doñana, and Logroño, referencing their publication in 'Stendek' or other sources like 'Keyhoe' and 'Fuller'.

Recurring Themes and Editorial Stance

The recurring themes in this issue are UFO sightings, encounters with humanoid figures, the role of child witnesses, photographic evidence, and the perplexing phenomenon of temporal anomalies. The editorial stance appears to be one of serious investigation into these reports, presenting witness accounts and photographic evidence for consideration, while also acknowledging the scientific analysis of such phenomena. The magazine encourages readers to contribute their own observations to maintain their archive.

This issue of "investigación" (Investigation) from October 1974 focuses on the quantitative analysis of UFO phenomena. The main article, "CONSIDERACIONES SOBRE EL TEST DE EXTRAÑEZA-CREDIBILIDAD." by José-Tomás Ramírez y Barberó, explores statistical methods to objectively evaluate UFO sightings.

Main Article: Considerations on the Strangeness-Credibility Test

The article begins by referencing Albert Adell's "TEST DE EXTRAÑEZA-CREDIBILIDAD," which provides a numerical and objective way to assess UFO observations based on two parameters previously identified by Dr. Allen Hynek. The author, inspired by V.J. Ballester Olmos's introduction, emphasizes the importance of "UNIVERSALIZAR" (universalizing) these concepts to refine them further.

The core of the article presents a method for globally evaluating a family of UFO sightings and obtaining a ponderal measure of their significance. This method involves using statistical tools: the regression line (RECTA DE REGRESION) and its linear correlation coefficient (COEFICIENTE DE CORRELACION LINEAL).

The author explains that the best representation of a set of points in a scatter diagram is a line that minimizes the sum of squared distances to those points, a method known as the method of least squares. This line is called the regression line of Y on X.

To illustrate, a hypothetical UFO flap is analyzed using four observations (A, B, C, D) that have been subjected to the Strangeness-Credibility Test. The article provides hypothetical data for these observations and their corresponding strangeness (W) and credibility (Y) values.

The article then details the mathematical conditions for determining the regression line:

1. First Condition: The regression line R must pass through the centroid (M) of the point cloud, which represents the mean of the abscissas and ordinates. For simplification, the coordinates are translated so that M becomes the origin, resulting in centered coordinates "x" and "y".
2. Second Condition: The slope "p" of the regression line R, defined as the tangent of the angle it forms with the horizontal, is calculated using the formula p = Σxy / Σx². The article provides a table with calculations for points A, B, C, and D, including their primitive and centered coordinates, xy products, x², y², and Σx², Σy², Σxy values.

From these calculations, the article determines that the regression line passes through M (x=5, y=4) and has a slope of p = 27/30 = 0.90. The equation of the regression line in the centered system is y' = 0.90x. This is then translated back to the original system as y = 0.90x - 0.50.

The article further explains that the sum of the squared deviations of the points from the regression line (Σe²) can be calculated using the formula: Σe² = Σy² [1 - (Σxy)² / (Σx² Σy²)].

It introduces the correlation coefficient "r" (COEFICIENTE DE CORRELACION LINEAL), defined as r = Σxy / √(Σx² Σy²). The article calculates "r" for the sample data as 0.96, indicating a strong positive correlation.

The significance of the correlation coefficient "r" is discussed in detail:

• r = 1: Rigid positive linkage (Y increases proportionally to X).
• -1 < r < 0: Negative correlation (Y decreases as X increases), becoming more precise as r approaches -1.
• r = 0: Independence of phenomena.
• 0 < r < 1: Positive correlation, becoming more precise as r approaches 1.
• r = -1: Rigid negative linkage (Y decreases proportionally to X).

The article concludes that the calculation of a regression line should always be accompanied by its correlation coefficient to precisely understand the relationship between phenomena. The example data (A, B, C, D) demonstrates a NET POSITIVE CORRELATION between the analyzed phenomena.

Other Sections and Articles

The issue also includes a section on "Nuevas Publicaciones" (New Publications), featuring a review of the book "Space-Time Transients and Unusual Events" by Michael Persinger and Gyslaine Lafrenière. This book proposes that UFO phenomena are triggered by variations in the Earth's geomagnetic field interacting with human brain bioelectricity, a theory described as daring and fascinating.

Several other articles are listed with their publication details:

• "A common physical model for Ball Lightning and Unidentified Flying Objects" by Mark Stenhoff.
• "A physical trace doth not a CEII make" by Allan Hendry.
• "Activités sismiques et phénomènes OV NI" by F. Lagarde.
• "Les pieces du puzzle" by Jean-Pierre Petit, discussing UFO propulsion problems.
• "Paralyse, l'arbre qui cachait la forët" by Jean-Luc Jorien, on paralysis effects experienced near UFOs.

There is also a profile of David G. Lopez, an investigator who founded a university group in 1967 to study UFO phenomena and was involved in organizing a seminar on the application of computing to UFO studies at the University of Madrid in 1972.

A brief mention of an artifact of 25 meters in diameter at 25 meters distance is made, assessed as POSITIVE, but with a NEGATIVE assessment of the witness's 'Culture Level' due to unknown details.

Recurring Themes and Editorial Stance

The recurring theme is the application of rigorous, scientific, and statistical methods to the study of UFO phenomena. The magazine promotes a rational and objective approach, moving beyond anecdotal evidence to quantitative analysis. The editorial stance appears to favor the exploration of unconventional hypotheses, such as the geopsique theory, while maintaining a critical and analytical perspective on the data and witness testimony.
