Geminid meteor shower

Thursday, 2017, December 14 (All day)

The Geminid meteor shower will reach its maximum rate of activity on 13 December 2017. Some shooting stars associated with the shower are expected to be visible each night from 7 Dec to 16 Dec.

The maximum rate of meteors expected to be visible from a dark location is around 100 per hour (ZHR). The Moon will be 26 days old at the time of peak activity, and so will present minimal interference.

The radiant of the Geminid meteor shower is at around right ascension 06h30m, declination +33°, as shown by the green cross on the planetarium above. At midnight, it appears 60° above your south-eastern horizon from London (click to change). All of the meteors will appear to be travelling directly outward from this point, as indicated by the white lines drawn above.

To see the most meteors, the best place to look is not directly at the radiant itself, but at any dark patch of sky which is around 30–40° away from it. It is at a distance of around this distance from the radiant that meteors will show reasonably long trails without being too spread out.
