    Cool Lunar X - 2021 MAY 18

    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.

    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 https://www.CurtRenz.com/moon.html
