(meteorobs) Leonids from Mongolia



We had a brilliantly clear night and observed from 15:30 UT to
22:45 UT. Rates were high over a long period, but the table
restricts mainly to the `core period`. The numbers hint at a
ZHR of about 4000. Numerous fireballs occurred with persistant
trains lasting up to 1/2 hour.

Here is the table with data collected from 5 observers of our group.
