Hi.

Very nice pictures. Does this X is visible every month ?

Andre.

The moon was my first telescopic object; it blew me away at age 13; it still does at age 69.

Elvis is a little more senior now so that is an older pic.

FWIW I have been doing serious observing for more than 3 decades. Obviously I am not an avid Lunar observer (unless outreaching) but I had not heard of the "X" until this year on these forums. Neat! The Straight Wall was my favorite small feature but the "X" might replace it. Got to look for it next month!

I have a complete Elvis outfit and have had a great time showing up at parties, with my wife, who wears a Priscilla outfit. I do a few pantomimes such as Jail House Rock and Hound Dog. When I am serious, I show up with my 12.5 inch Portaball instead.

No, sometimes it happens in daylight or just not a good observing window of opportunity. Click on the link above and you can see what the times are each month. He has highlighted the best dates and time for viewing and then you have to convert the times to your viewing area.

If you miss the X you can catch this feature a few days later in the WURZELBAUER crater:-)

The Lunar X, which is also known as the Werner or Purbach Cross, is an X-shaped clair-obscur illumination effect involving various ridges and crater rims located between the craters La Caille, Blanchinus, and Purbach.

I haven't looked for the 'x' before but after reading this thread I see I video taped it.

moon thru my new dob you can see a close up of the 'x' at 1:36 on the time slider.

thanks everyone for posting their 'x's.

I really need to get something to hold that vid cam inplace, hand holding is obviously not for me.

Had a great view with ED80sf, Burgess binoviewer (w/ OCS) and a pair of 20mm binolites. Got a quick video capture using a pocket DVR with dashboard-cam-to-1.25" adapter.

Does anyone have a link to 2013 Lunar X schedule?

Approximately for how long is this X visible for? Several minutes? Several hours?

After you view it on the best night try looking at the same spot on the following night. It will give you a better understanding on how the view is formed.

Has anybody seen this new tool from NASA? http://svs.gsfc.nasa.gov/vis/a000000/a004000/a004000/
It lets you plug in a date and time and you can see exactly what the moon will look like. It only works for 2013 though.

Before clouding up his lens', aaron caught this terrific feature days before Thanksgiving. I thought it would appear monthly, but one would have to catch 'it' near 1st quarter (or just beyond).

And it is really neat getting to view everyone's different angles & perspectives of "X" (i wanna say, as i followed the 'terminator'(?) up i also caught glimpses of a V shape that also shined brightly, but not nearly as bright as the X.) & to think.... i was only after a better view of the crater/caldera of Tycho!
