Astronomical Calendar 2013 Astronomy Events
03.04 January 2013 - Quadrantid meteor shower, get to have up to 40 meteors per hour, usually on 3 and 4 January, but may be visible on 1-5 January. The highest rate of meteors per hour took place in 1932 (80/ hour). The best time for observations is a dark place after midnight. Meteors radiate from the constellation Bootes, close to the North Star.
The source of this meteor shower was unknown until December 2003 when Peter Jenniskens of the Ames Research Center (NASA) found evidence that meteoroids come from 2003 EH1 , an “asteroid”, which is probably a piece of a comet which collapsed 500 years ago.

The peak of the shower usually occurs around December 13 & 14, although some meteors should be visible from December 6 - 19. The radiant point for this shower will be in the constellation Gemini. The gibbous moon could be a problem this year, hiding man of the fainter meteors. But with up to 60 meteors per hour predicted, this should still be a good show.
