On February 17, 2013, a witness in Brest, France, observed a bright luminous point traversing the night sky before suddenly disappearing. The witness reported observing this identical phenomenon at the same time on two separate occasions, fifteen days apart. The object appeared as a high-intensity light point that passed overhead before vanishing abruptly at approximately 20:04 local time.
GEIPAN investigators conducted a thorough analysis using Calsky satellite tracking data for the Brest area on the evening in question. The investigation revealed that the Cosmos 2297 Rocket (catalog number 23405 1994-077-B), the third stage of a Zenit-2 launcher originally deployed from Baikonur on November 24, 1994, entered Earth's shadow at precisely 20:04—the exact moment the witness reported the object's disappearance. This timing correlation provided definitive identification of the observed phenomenon.
The investigation noted that numerous satellites of varying brightness are regularly visible from Brest during this evening hour and season, though weather conditions are not always favorable for observation. GEIPAN classified this case as 'A' (identified with certainty), confirming the sighting as the third stage booster of the Zenit-2 launcher that deployed Cosmos 2297, which remains in orbit alongside the satellite itself.

04 Analyst Notes -- AI Processed
This case represents a textbook example of satellite misidentification and demonstrates the value of systematic investigation using astronomical tracking data. The witness's observation of the phenomenon occurring at fifteen-day intervals at the same time strongly suggests a recurring orbital pass, which is consistent with satellite behavior. The credibility of the sighting is enhanced by the witness's attention to detail and the repeatability of the observation.
The GEIPAN investigation's use of Calsky satellite tracking data provided conclusive identification. The precise temporal correlation between the object's disappearance (20:04) and the Cosmos 2297 Rocket's entry into Earth's shadow eliminates reasonable doubt about the identification. This case illustrates how bright satellite passes, particularly rocket bodies which can be highly reflective, are frequently mistaken for anomalous phenomena when they suddenly disappear as they enter Earth's shadow. The witness's description of 'high intensity' is consistent with sunlight reflecting off the large surface area of a rocket booster.

BELIEVER ANALYSIS
SKEPTIC ANALYSIS
Mundane Satellite Observation
This case demonstrates how unfamiliarity with routine satellite passes can lead to reports of unexplained phenomena. The witness likely had limited experience observing satellites and was unaware that dozens of satellites and pieces of space debris are visible on any clear night. The 'sudden disappearance' that seemed mysterious has a straightforward astronomical explanation. The investigation conclusively shows this was a routine observation of known space objects.
06 Verdict
ANALYST VERDICT
This case is conclusively explained as the observation of space debris—specifically the third stage of the Zenit-2 rocket that launched Cosmos 2297 in 1994. The investigation demonstrates high confidence in this identification based on precise timing correlation, orbital mechanics, and the repeatability of the sighting. While the witness may have been genuinely puzzled by the sudden disappearance of the bright object, this is a well-understood optical effect that occurs when satellites enter Earth's shadow and are no longer illuminated by the Sun. This case holds minimal significance as an unexplained phenomenon but serves as an excellent educational example of how rigorous investigation and astronomical data can resolve apparent mysteries. The GEIPAN 'A' classification is entirely appropriate.
