LTVT strikes again! I really should take some time and learn to use that program. Thanks for the explanation, Jim--and your correct time, Larry. (0617 was correct for the end of the capture which went for about two minutes). Two hours difference surprises me a bit, though i do not doubt it as a fact now. But this is why it fooled me:
Left is an earlier shorter capture (interrupted by a heavy truck passing on the nearby street--which does a nice imitation of a small earthquake...) and the other the one posted earlier. I noted the significant changes in the illumination of the peaks and assumed (bad idea) that this increase in illumination rate was more or less constant. I never looked quite this closely at the *rate* of emergence of peaks past the terminator before--obviously it starts out quite fast and then slows down considerably as the light begins to creep down the slopes after rather quickly illuminating the tops of the peaks. Very interesting! It's amazing what one learns through a bit of close study of some lunar images.
