Hi all
I've just finished an observing session, yeah, remember what they were?
Anyway, I was observing doubles in Aquila, report to follow later today, and when I finished the moon was high in the east so I turned to it. Skirting the terminator at 206X I stopped at Sacrobosco and there was a fat W shape at the base of the crater formed by the shadows crater wall. It was so obvious, I have heard of the lunar X and now I believe that I can add a W. The observation took place at 00.25 UT
