OK so i am really trying to determine the EXACT date I got started in amateur astronomy. Using a 40X Gilbert 2 1/2" reflector and a moon map my 8th grade science teacher gave me, I examined the Moon in late April of 1974 and was hooked. Using the map (I still have it) I thought I "discovered" a new crater and excitedly told my science teacher the next day! I now know it was the crater "Dembowski" near Agrippa and Godin. Agrippa and Godin are on this map, but Dembowski wasnt. Now the fact that I could pick up Dembowski in THAT telescope may be the clue I need to pinpoint the date....maybe. April 29, 1974 or April 30, 1974 are both feasible candidates. I certainly can find the actual phase of the moon, but I need to see exactly where the terminator was on both of those dates in relation to Dembowski and of course libration can severely affect that. Anyone know of a website that takes libration into account where I can type in the date and see what the moon actually looked like from my location on that 47 year ago night? I want to determine this before my 50th anniversary of observing rolls around. I plan also on going to the public library and getting the old newspaper from that date to make sure the weather was clear on the night in question.
