September 22, 2012, our astronomy club set up our scopes during a dressy fundraiser dinner called "Wine Under the Stars". The purpose was to benefit the local Science Center where we hold our meetings. It just happened to be the same evening that the X was visible. After a few people came to the scopes, the word spread rapidly that there was an X on the moon. What a hit! We had lines all night. It really engaged people to the event and increased interest in our club.

Nice sketch. I could kick myself for not taking the time at the eyepiece to attempt to document what I see. I keep all the drawing materials right there in the observatory but fail to do it.  Thanks for sharing. Be well Grey

I think the first "X" I caught was on my 1st afocal shot with my first digital camera. I didn't know how many people who would like a shot keep getting clouded out during those few hours it's visible. Nice shot BTW Be Well Grey

Thanks. It would be nice to see that first "X" you caught if you still have it, thanks.

Sorry that photo died along with a hard drive in a computer that died a long long time ago in a galaxy far far away.
I hope your success in your capture encourages you to keep shooting the sky. Be Well Grey

Thanks, Carol, you taught me all I know, but I think I can do better. I was making pretty rough sketches to capture the evolution of the X, not trying too hard to include all the subtle variations in grey level. It was pretty cold out!

Here's my rough drawing from 9:30 p.m. AST. I used a 12" Sky-Watcher f/5 with a 6 mm eyepiece for 250x.

Do the Lunar X features appear when the moon's waning terminator crosses the same coordinates?

Yes it does - see the Purbach Cross (Lunar X) - Sunset Viewing Project thread in this forum. I posted a composite picture comparing the sunrise and sunset views.

Good job. Just a little up from your pic top is the Lunar "V". You have a chance to catch this again tomorrow (Sunday the 17th of Feb). Here in Tucson it occurs at 3:30 in the afternoon, but at 49 degrees Alt it should be visible.

Looks like I can expect clouds where I'm at... Maybe I'll see something before it's too late...
