Stationary then erratic spherical object — Los Alamos (Feb 24 1950, Sighting 179)

Feb 24, 1950Los Alamos, New Mexico (approx.)
Analysis — our summary

A spherical, aluminum-colored object was observed at Los Alamos on 24 February 1950 (Sighting 179 in the 17th District OSI summary). It was reported as circling then moving eastward at considerable altitude. The object was evaluated by the 17th District OSI as Classification (1) — Green Fireball Phenomenon — and rated with reliable observers. Dr. LaPaz analyzed this class of object extensively throughout his reports.

Analyst notes — caveats & confidence

Extracted from heavily OCR-corrupted tabular summary (pages 33–34). Text partially reconstructed from adjacent legible fragments. Classification (1) = Green Fireball Phenomenon (not necessarily green color; OSI's classification for anomalous aerial objects under investigation). Confidence is moderate-low given OCR noise. Included because the description of a spherical metallic object with maneuvering behavior is qualitatively distinct from the green fireball flightpath cases.
