Stationary white-amber circular object, then accelerated — Alamogordo (Dec 13 1949, Sighting 159)

Sighting 159 from the 17th District OSI summary table: at 20:05 on 13 December 1949, three reliable observers reported a circular object at approximately 5,000 feet over Alamogordo, New Mexico. Initially stationary with white-amber-red coloration, the object then began to move, assumed a brilliant green color, and 'picked up speed.' The object was estimated at 1–1.5 times the size of an average streetlight at distance.

Extracted from heavily OCR-corrupted tabular summary (page 29). Three reliable observers (R rating). Evaluated as both Classification (1) Green Fireball Phenomenon and Classification (2) Disc or variation — unusual dual classification suggesting behavior crossing both categories. Color change from white/amber to brilliant green on acceleration is noteworthy. Confidence is moderate-low due to OCR noise in source table.
