Lunar orbit

During the Apollo 11 Technical Crew Debriefing on July 31, 1969, Buzz Aldrin described three observations from the mission. Approximately one day from the Moon, the crew spotted an object of sizeable dimension that appeared L-shaped through the monocular and like a hollow cylinder through the sextant; ground control confirmed the S-IVB stage was 6,000 miles away, and the crew reached no conclusion about the object's size, range, or identity. Aldrin also reported recurring small flashes of light inside the darkened cabin, spaced roughly a minute apart, which he guessed were caused by some penetration of an object into the spacecraft.
