(meteorobs) a fireball video

[esko.lyytinen at jippii.fi]

Hi,

You can see the video of a recent fireball at:
http://www.ursa.fi/ursa/jaostot/meteorit/images/Tulipallo_20060326_190153_Vaala3.mpg

This happened in Mar. 26 at 19:02 UT.
This video is from Jarmo Moilanen at a distance of about 250km:s from 
the fireball.
I also captured this fireball near horizon at a distance of about 700km:s.

Unfortunately these two observing stations are almost at the same line 
with the fireball. So not very accurate entry path can be calculated.
It appears that probably an about one kilogram meteorite fell about 20 
to 30 kilometers outside of the eastern border of Finland, in the side 
of Russia.
We have also received quite a number of visual observations but these 
all were from south to west of the fireball.

We have had quite a lot of fireballs since about Jan 19 here in Finland. 
Two of them are expected to have been quite a lot bigger than the most 
recent. One was a bright daylight fireball in Feb 14 (at about 06:50 
UT), but meteorite fragments seem to have fallen to the sea area west of 
Finland. Another BIG one appeared in Feb 7 at 01:47UT (03:47 local 
time).
This is expected to hava fallen a considerable big meteorite in a lowly 
populated area in northern Finland, but it weas not captured in fireball 
videos (some light spot in the clouds(?) near horizon may appear in my 
video data). There are only a few visual observations accurate enough 
for the entry path modeling and only two near the end of track. These 
two appear quite reliable, mutually consistent but will not pinpoint the 
landing site exactly enough for a reasonable search. The end height 
appears to be as low as about ten kilometers, and this with a relatively 
low entry angle (about 20 degrees). This is one thing to tell on the big 
size! This did not seem to fragment, except maybe a few small pieces 
left behind.

Best wishes,
Esko
