The Geminid meteor shower will reach its maximum rate of activity on 13 December 2020. 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 is around 100 per hour (ZHR). However, this assumes a perfectly dark sky and that the radiant of the meteor shower is directly overhead. In practice, the number of meteors you are likely to see is lower than this, and can be calculated from the ZHR formula.
From Ashburn (click to change), the radiant of the shower will appear 52° above your eastern horizon at midnight. This means you may be able to see around 79 meteors per hour, since the radiant will be high in the sky, maximising the chance of seeing meteors.
The radiant of the Geminid meteor shower is at around right ascension 07h20m, declination +33°, as shown by the green cross on the planetarium above. All of the meteors will appear to be travelling directly outward from this point, as indicated by the white lines drawn above.
The Moon will be 29 days old at the time of peak activity, presenting minimal interference.
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.
