Gemini 7 astronauts (December 1965) reported a 'bogey' alongside a field described as 'hundreds of little particles' at an estimated 4 miles distance in low Earth orbit, with the encounter annotated contemporaneously as a 'UFO Sighting.'

Frank Borman distinguished the phenomenon from simple debris; James Lovell described a 'brilliant body in the sun against a black background with trillions of particles.' The spacecraft annotation shows the anomalous nature was recognized real-time.
