This information paper from the Department of Defense's All-domain Anomaly Resolution Office (AARO) is dated December 2024 and was released in full in February 2025. It explains how sunlight reflecting off Starlink and other low Earth orbit satellites produces bright flares and satellite trains that observers can mistake for UAP. It gives step-by-step methods for predicting flare windows from the ground and from aircraft. It concludes that lights reported by an airline pilot near Gallup, New Mexico, in October 2022 were very likely satellite flares.
