The Lunar X may be seen by telescopic observers in much of North America during the night of 2019 APR 11-12 for an approximately four-hour period centered on APR 12 at 01:02 CDT (06:02 UT). 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.

My timetable for when the lunar terminator will be crossing select lunar features such as the Lunar X and rayed craters can be found at
