Friends,
Following is a preliminary report of the Leonids meteor shower for the
night of November 17-18, 1999 from Israel.
Observing location: Mitzpe-Ramon, Israel
Observing time: 22:30UT November 17 - 03:30UT November 18
Weather Conditions: Near perfect weather. Very few thin Cirrus clouds. Dry
and calm. Temperature ~15 degrees Celsius. Limiting Magnitude ~5.5.
Observers: 4 separate groups, counting in total 30 observers.
Results: Amazing display. Peak at about 01:54UT, with the radiant almost
overhead. An estimated rate of ~70 meteors per minute, i.e. >4,000 meteors
per hour, maybe closer to 5,000 meteors per hour. Persistant duration of
this rate for ~34 minutes! Most meteors in the magnitude range of 1 to 5,
with a few fireballs leaving trails for up to 20 seconds.
Impression: The best meteor shower witnessed by many. Only last years'
unexpected Leonids fireball show on the night of November 16-17, 1998
outperformed this year's show, but only from the aspect of bright meteors
count, not total number count.
