On the morning of January 13, 1979, between 6:15 AM and 8:30 AM, a single witness observed a bright luminous point from their residence in Saint-Mandé, a commune in the Val-de-Marne department of the Île-de-France region. The witness was sufficiently intrigued by the object to photograph it multiple times during the observation period. The luminous point moved slowly from east to west along an ascending trajectory across the sky.
The witness's detailed description and photographic evidence were analyzed by GEIPAN investigators in conjunction with astronomical charts for that specific date. The investigation revealed that the observation corresponded precisely with the position and movement of the planet Venus, which was exceptionally visible during this period with a magnitude of -4.41, making it extraordinarily bright in the pre-dawn sky.
GEIPAN classified this case as "A" classification—the highest level of certainty indicating a positive identification with a conventional explanation. The witness's photographs and testimony, when cross-referenced with astronomical data, provided conclusive evidence that the observation was of Venus during a period of maximum visibility.
02 Timeline of Events
06:15
Initial observation begins
Witness first notices a bright luminous point in the sky from their residence in Saint-Mandé. The object is bright enough to attract attention in the pre-dawn hours.
06:15-08:30
Extended observation and photography
Over the course of more than two hours, witness observes the luminous point moving slowly from east to west along an ascending trajectory. Multiple photographs are taken to document the phenomenon.
08:30
Observation concludes
The observation period ends as the object continues its westward movement. Witness has collected photographic evidence and detailed observations.
Post-incident
GEIPAN investigation initiated
Case reported to GEIPAN. Investigators analyze witness testimony, photographs, and compare with astronomical charts for January 13, 1979.
Post-incident
Astronomical correlation confirmed
GEIPAN analysts determine that all witness observations correlate perfectly with Venus at magnitude -4.41, which was at maximum visibility during this period. Case classified as 'A' - positively identified.

Resident of Saint-Mandé who observed the phenomenon from their home and took the initiative to photograph it over an extended period. Demonstrated good observational discipline by noting specific details.
04 Analyst Notes -- AI Processed
This case demonstrates the importance of astronomical cross-referencing in UAP investigations. The witness demonstrated good observational discipline by photographing the phenomenon and noting specific details including timing, direction of movement, and trajectory. The fact that the witness was sufficiently intrigued to document the sighting over a 2+ hour period indicates the brightness and unusual appearance of Venus during this particular astronomical configuration.
Venus is one of the most common sources of UFO reports, particularly when it appears as a morning or evening star at maximum magnitude. With a magnitude of -4.41 on this date, Venus would have been exceptionally bright—bright enough to be visible even as dawn approached and to cast shadows under certain conditions. The reported east-to-west ascending trajectory is entirely consistent with Venus's apparent motion during morning observations as the Earth rotates. The witness's honesty in reporting what they saw, combined with GEIPAN's thorough astronomical analysis, makes this a textbook case of proper investigation methodology leading to positive identification.
05 Theory Comparison
BELIEVER ANALYSIS
SKEPTIC ANALYSIS
Common celestial misidentification
Venus accounts for a significant percentage of UFO reports, particularly when appearing as morning or evening star at peak brightness. The witness's genuine curiosity and documentation efforts, while commendable, reflect a lack of familiarity with astronomical objects. The two-hour observation period, while seeming unusual to the witness, is simply the result of observing a planetary object during morning twilight as Earth's rotation creates apparent motion across the sky.
06 Verdict
ANALYST VERDICT
This case is conclusively explained as an astronomical observation of the planet Venus. The GEIPAN investigation leaves no doubt: the witness's description, photographic evidence, and timeline perfectly match Venus's position and exceptional brightness (magnitude -4.41) on January 13, 1979. While the witness was genuinely intrigued by what they observed, all evidence points to a natural astronomical phenomenon. This case exemplifies how even experienced observers can be misled by common celestial objects under optimal visibility conditions, and demonstrates the value of systematic investigation using astronomical data. The "A" classification is entirely justified, and this case holds minimal significance beyond serving as an educational example of Venus misidentification.
