The Moon just past full will occult (cover) the stars Eta Geminorum (Mag +3.3) and Mu Geminorum (Mag +2.9) during the night of 2019 DEC 12-13. Both events will be observable from most of North America, but only the former event for much of Europe.

The upcoming immersions will occur on the lunar dark limb and emersions on the bright limb. Any observers on a graze path can witness a star winking on and off as lunar hills and valleys pass by. Those between the two paths will see a full occultation.

Iíve created North American graze maps, sets of Besselian elements for computer input, and preview graphics with data for Chicago. They can be seen by visiting my Occultations webpage at https://www.CurtRenz.com/occultations.html

Photos and descriptions of the occultations would be welcome additions to this thread. If you would like specific occultation or graze predictions for your location, please reply to this post with your longitude, latitude, elevation and time zone.
