Lunar X - 2021 MAY 18-19

[CentaurZ]

The Lunar X may be seen by telescopic observers on either side of the Atlantic Ocean during the evening of Tuesday 2021 MAY 18 for an approximately four-hour period centered on 20:08 CDT (MAY 19 at 01:08 UT). This would be a nighttime event for most observers, but an afternoon one for those in western North America. For Europeans the Moon may set while the Lunar X remains visible.

The X should appear as the Sun rises on the clustered rims of the craters Blanchinus, La Caille and Purbach, while a waxing nearly Half Moon graces the sky.

This is something to check-off from your astronomical “to-do” list. Photos and descriptions of the Lunar X would be welcome additions to this thread.

Looks like it should be visible around midnight 18th/19th in the U.K. with the Moon at 21 degree altitude. Worth a go!

I was looking at the moon last night and managed to see the X; not as obvious as if it were a day earlier (but all cloudy). I managed a quick shot with my mobile and the EP. The crop is from the same full moon image.

Cool. I knew about the V; I can see the others  in my pic now. Viewing was really good/sharp last night although it did not take high magnification very well.
