In November 1969, during Apollo 12's fifth mission day, Lunar Module Pilot Alan L. Bean reported an "all s flash" pulsing every second on both the address and information registers of the AGS, at about one-fifth the brilliance of the normal numbers. Houston attributed the phenomenon to EMI, citing similar observations during ground testing of spacecraft at Bethpage. On the sixth day, Command Module Pilot Dick Gordon reported that the Lunar Module Intrepid's blinking tracking light had stopped blinking and he could not acquire Intrepid in the sextant.

Particles and flashes of light observed via the Alignment Optical Telescope (AOT), described as 'sailing off in space' and characterized as 'escaping the Moon'
