Astronomical Calendar 2013 astronomy events

Now that we've passed 2012, after the Mayan calendar is also done, let's continue our Julian calendar with Astronomical Calendar 2013 astronomy events.
This calendar will be modified with events which will appear in time, such as evolving asteroids or other objects in the sky.
Here's how it looks:


01 January 2013  -Comet P/1996 R2 (Lagerkvist) Closest To Earth (2.546 AU).

02 January 2013  -Comet C/2011 UF305 (LINEAR) Closest To Earth (1.917 AU)

03.04 January 2013 - Quadrantids. 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.
