The Largest First Quarter Moon of the Year

 

December 18th, 2015

With the completion and publication of my latest book, Easy Things to See With a Small Telescope, I haven’t had a lot of time (and energy) to post about recent astronomical events. Having said that, all of the visible planets can only be seen in the pre-dawn sky leaving the evening hours to be occupied by the Moon – and the Geminid meteor shower.

Today the Moon reaches first quarter, thereby making it visible throughout till about midnight, and dimming the light of faint Pisces. It also happens to be the largest first quarter Moon of the year, although you’re not likely to notice any observable difference in size.

In just a week, the Moon will turn full on December 25th, for the first time since 1977. By itself, this doesn’t mean much, but for me, it marks an important anniversary. For it was on Christmas Eve, 1977, that I first became fascinated by the stars… but that’s a story for another time.
