(meteorobs) Fireball News Article from Finland

[Lyytinen Esko]

Hi,

Yes we really had a very bright fireball yesterday evening at about
19.23 UT.

The URSA meteor section has received quite a big number of reports and
more is coming.

The Sun was just about setting at the the region of the observations and
it was very remarkable in spite of the lightness. It was cloudy here in
Southern Finland and so I could not capture it in my fireball-camera.

We have received one photograph of the smoke trail that peristed for 45
minutes (maybe till the Sun got too down to illuminate it). There also
exists a video of the smoke trail, but the recoreder has not yet
submitted it.

According to my quick lookup, this seems to be clearly visible in the
Swedish infrasound data from http://www.umea.irf.se/maps/index.php
Uppsala and Lycksele .

It appears to have entered from somehere South-East with an entry angle
of maybe 30 degrees from horizon and lasted maybe from 5 to 10 seconds.
So the entry velocity seems to have been relatively slow.
According to one (of the most nearby observers it exploded into small
pieced that ended in less than a second from the explosion.)
The pieces quite clearly landed ouside the Finnish border, into the
Russian side, maybe by about/more than 100km:s, according to the
infrared locator.

I expect that Markku Nissinen will put the smoke trail-figure into the
URSA meteor section web-site, but this has not yet been done.

There's a brief fireball news article from: NewsRoom Finland

A rare atmospheric phenomenon occurred in Finland late on Tuesday night.
Emergency authorities in North Karelia received around twenty telephone
calls alerting them to what was later confirmed as a fireball, or an
especially luminous meteor.

Callers told the authorities that a burning object fell from the sky
leaving a smoke trail...

Any URSA meteor-section members here?
