The Lunar X may be seen by telescopic observers in Europe and the Americas during Wednesday 2018 JUN 20 for an approximately four-hour period centered on 15:28 CDT (20:28 UT). This will be an evening event in Europe and an afternoon event in the Americas. The X should appear as the Sun rises on the clustered rims of the craters Blanchinus, La Caille and Purbach, while a waxing 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.
