Hello,
An obsrvation on 12 December. The temperature dropped to -27-28 C, and
under the bright Moon and some cirrus
clouds lm was only at 4.1 mag. The Geminids showed activity with five
meteors during Teff=0.93 h, also I saw
2 sporadics.

Also, other observations around max. time of Gemininds show activity
of about 10-15 meteors per hour with lm ~5.5 mag. This gives max. ZHR not
more than ~50. Were Geminids a lull this year?
