My second session of the night saw an increase in rates from a few hours ago. Between 4:57 am (11:57 UT) and 5:49 am (12:49 UT), I counted 30 meteors of which 22 were Geminids. The sky was significantly darker than a few hours earlier with a limiting magnitude of +5.7. A quick calculation gives a ZHR of ~81 which is an improvement over the ZHR of ~68 I measured before.
Tomorrow morning should see a 50-100% increase in rates compared to tonight.
I’ll have the video results posted sometime during the day.
