Went to the space shuttle page and noted he was saying the bright moon itself could cause a shadow in our atmosphere when the sun was setting and not as bright. Problem with that theory is we had a new moon Saturday. No moon light or almost no moon light on Monday.
No moon light at what altitude? He claims he figured in the position of the moon at the time. I see you took the discussion straight to him on the other thread. Good thinking. I hope he replies. If he does please ping me to it.
