December 29 - Look to the east in the late evening to locate the bright waning Moon, and right above it, the bright star Regulus, the brightest star in the constellation Leo, and one of the brightest stars in the night sky, with a bluish tint. Part of the constellation Leo includes up a backwards question mark and Regulus provides the dot at the bottom.
Try to locate Jupiter low in the horizon after midnight.
Oh, about that Christmas Full Moon…
The full moon hasn’t fallen on Christmas Day since 1977.
December 8 – Earliest sunset of 2015 at 4º0 N. latitude.
December 11 to 13 – Get ready for the annual Geminid Meteor Showers!
They are visible all weekend and they’ll peak on December 13. They’re considered the best meteor showers of the year.
The radiant — that spot in the sky where the meteors will appear to emanate — lies just below and to the right of the bright star Castor in the constellation Gemini (hence the name, “Geminids”). Best viewing after midnight until dawn.
December 11 – New Moon at 5:29 a.m. It is completely invisible to the naked eye.
