The waxing gibbous moon will block out most of the fainter meteors this year. But the Geminids are so numerous and bright that this could still be a good show. Best viewing will be from a dark location after midnight.
The Geminids is the king of the meteor showers, and it is thought to be intensifying every year. Recent showers have seen 120–160 multicolored meteors per hour under optimal conditions, generally around 02:00 to 03:00 local time.
These meteors are the debris left behind by an asteroid known as 3200 Phaethon, which was discovered in 1982. The shower runs annually from December 7-17. It peaks this year on the night of the 13th and morning of the 14th. The morning of the 15th could also be nearly as active this year. Meteors will radiate from the constellation Gemini, but can appear anywhere in the sky.
