(meteorobs) Leonids Summary Report from Thailand
Dear all,
We observed from Khao Yai National Park, Nakhon Ratchasima, Thailand at
Long. 102° E. Lat. 15° N.(approx.) between Nov 16, 14-23UT and Nov 17,
17-23UT (during the night in Thailand). This report is delayed because I
just come back to Bangkok. I'm not an experienced observer, I think my
result may not important for serious study, but I have summary of the
event here;
16 November, 14-23 UT
---------------------
Because of prediction of the peak on Nov 17, 19UT and full of thin
smoke in the skies. I never expect much about the shower on this night.
BUT...
- hours before the radiant of Leonids rise around 17UT, we saw some of
Taurids.
- around 17UT, a "GRAZING leonid" passed about 140º-150º across the sky
from east to west (nearly exact direction), it was very bright and
spectacular (I never see something like this).
- afterthat, 4-5 leonids which extremely bright passed from radiant in
and perpendicular to the horizon plane.
- first hour after midnight (17-18UT), we saw 18 leonids.
- rate of leonids increasing with the radiant rising, more of them
produced persistant train which lasted from several seconds to minutes,
I can say that the
Leonids this night are rich of bright meteors, numerous fireballs, and
many exploded.
- around 22-23 UT, we approx. that the rate was 4 per minute.
- 540+ bright Leonids appeared from 17-23UT.
- SPECIAL: Nov. 17, 2:42 UT (+/- 1 min.), I accidently saw a
brief-lasting fireball in the daytime (it was 9:42 local time with
high-elevation of the Sun in the sky). I expected that someone can see
this extremely bright fireball in the night sky.
17 November, 17-23 UT
---------------------
Because I can't connect to the internet there, I did't know that it was
after the peak in Atlantic, thousands of observers in Thailand went out
of home to our observing location to wait for meteor storm. It was
disappointing. Few of meteors appeared, we counted 170+ Leonids from
17-22.5 UT (it's far less than last night).
