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.
All-domain Anomaly Resolution Office (AARO) 2 comparable to starlight. Due to their construction and orientation, many man-made satellites in LEO diffusely reflect sunlight and can appear as stars that move across the night sky. Figure 1: Graphic of Starlink satellites in orbit. Ref: https://www.heavens- above.com/StarLink.aspx Specular reflection, also known as glint, occurs from a very smooth, mirror-like surface as illustrated on the right side of Figure 2. Unlike diffusely reflected light, the light striking a smooth surface reflects light at the same, or nearly the same, angle as the incident light. Therefore, the reflected light cone from a satellite in LEO is much narrower for specular reflection as compared to diffuse reflection, as illustrated in Figure 3(b). This dramatically increases its observed brightness by several orders of magnitude, but greatly decreases its observation time as the cone passes over the observer.
