Of course my calculated lunar distance didn't include the mistake, else the result would have been completely wrong. Solution to the "lunar time sight" is 00:02:05 UTC per my Lunar program. With the method of Chauvenet and calculated altitudes I get 2 seconds later and 28.04964° "cleared" lunar distance, i.e., the observed LD with estimated refraction and parallax removed. -- Paul Hirose sofajpl.com
