On January 3, 1979, two separate sightings occurred in Saverne, Bas-Rhin department, France, both reported to GEIPAN. The first observation took place at 6:50 AM when two witnesses observed a brilliant object at low altitude in the south-southeast direction. They described the object as hemispherical, accompanied by a shower of sparks, moving progressively and silently before disappearing toward the south. GEIPAN's astronomical analysis determined this was likely an observation of Venus, which was particularly visible in the sky during this period with a magnitude of -4.46.
The second sighting occurred the same day at approximately 7:00 PM when a motorist observed a different aerial object. For 3-4 seconds, the witness saw a sphere moving silently at very high altitude on a north-south trajectory. GEIPAN investigators assessed this second sighting as probably a weather balloon (ballon-sonde), though they acknowledged lacking sufficient information about this particular object.
The case received a Classification B from GEIPAN, indicating a probable explanation with good consistency between witness testimony and the proposed identification. The morning sighting's explanation is particularly strong given Venus's exceptional visibility at that time, while the evening sighting remains more speculative due to limited observational data.

04 Analyst Notes -- AI Processed
This case demonstrates the value of astronomical cross-referencing in UFO investigations. The morning sighting's description of a 'hemispherical object with sparks' is consistent with Venus viewed through atmospheric distortion near the horizon, particularly during morning twilight when the planet would appear low in the southeast sky. The magnitude of -4.46 would make Venus extraordinarily bright and potentially create the 'sparkling' effect through atmospheric turbulence. The witnesses' description of 'low altitude' is typical of misperception when viewing celestial objects near the horizon.
The evening sighting presents less certainty. While weather balloons are common and the brief 3-4 second observation window, silent movement, and high altitude are all consistent with a balloon, GEIPAN's acknowledgment of insufficient data is notable. The north-south trajectory and spherical shape are compatible with balloon hypothesis, but without meteorological service records confirming a launch, this remains speculative. The two unrelated sightings on the same day in the same location may suggest heightened awareness or reporting bias after the morning incident.
05 Theory Comparison
BELIEVER ANALYSIS
SKEPTIC ANALYSIS
Reporting Bias Following Initial Sighting
The occurrence of two separate sightings in one day may indicate heightened awareness and reporting bias. After the morning Venus sighting generated discussion, the motorist may have been primed to notice and report ordinary aerial phenomena like a balloon that might otherwise have gone unremarked. This psychological factor could explain the temporal clustering of reports.
06 Verdict
ANALYST VERDICT
This case is confidently assessed as explained for the morning sighting and probably explained for the evening observation. The morning Venus identification is supported by strong astronomical data and typical misperception patterns when viewing bright planets near the horizon. The Classification B rating appropriately reflects high confidence in this explanation. The evening sighting, while less certain, fits the weather balloon profile and lacks any characteristics suggesting anomalous phenomena. This case is significant primarily as a teaching example of how celestial bodies can be misidentified, and demonstrates GEIPAN's methodical approach of distinguishing between well-supported explanations and probable-but-uncertain ones.
