Skylab 3 crew observes multiple flashing exterior lights during orbit — Earth orbit

Skylab 3 crew reported observing lights flashing outside the station with definite motion relative to the spacecraft on two or three occasions during the mission. These were presumed to be other pieces of Skylab debris or co-orbiting satellites. One or two appeared to be tumbling. Events were logged on dump tapes.

“CARR: "on occasion we saw some lights flashing outside with very a definite motion relative to ours. We presumed that they were other pieces of Skylab, or possibly other satellites. We reported our two or three sightings of that kind as soon as they occurred."”

This section belongs to the Skylab 1/4 debriefing (JSC-08809, February 22, 1974) which is the fourth document merged into this file. Speaker identifications include Carr (CDR) and Pogue/Gibson (other crew). The crew's own explanation (debris or satellites) is plausible but unverified. Reported to ground in real time via dump tapes. OCR quality is fair.
