Astronomical phenomena December 2013

Calendar with astronomical events of December. The most important event for amateur astronomers this month should definitely be comet ISON which this month it would had make its appearance in our sky, most likely to be seen with the naked eye. But, on November 28, comet ISON in which we've put so much hope that it would be spectacular in the sky of December, suffered an "accident" at the meeting with Sun unfortunately. Best photos of the comet remained those from November.

13, 14 december 2013 - Geminid meteor shower- is considered by many to be the best meteor shower on the the sky. Geminids are known to produce up to 60 multicolored meteors per hour at their peak. Most usually appear on, or around 13 by December and 14, although some meteors should be visible between 06 and 19 December. They radiate from the constellation Gemini and originates from the asteroid 3200 Phaeton. This year, New Moon will guarantee a dark sky, so it would be a wonderful show. The best observation is to the east after midnight in a dark area.
