As I said, it was 2 in the morning, I was at the computer working on something because I couldn't sleep, and I hear what I would have sworn was Neil Armstrong's voice mentioning something about some light on the horizon. The TV was way down so it wouldn't wake my wife up, but I really thought I heard something. By the time I could get up and get a remote, the program ended, and I never did find out what it was.
I'm now pretty much convinced I don't know what to make of it.
Was there, or was there not something that was "luminous" mentioned on 11, from the surface, either during the EVA or shortly after? I've read through the transcript, and I remember a mention of a light near Aristarchus, but that was Collins from Columbia talking about soil or ejecta or some reflection (I haven't memorize the thing, and its been a few days since I skimmed through it.)
At this point, I'm absolutely not sure what I remember hearing. I'd make a lousy eyewitness.
