A fireball at night, brigter than the venus - 26.12.2018 at 00.10 Kiiminki Observation number 79888

Visibility III / V

Pekka Kangas, Oulun Arktos

It was a brisk go: in a few seconds below the Little Bear over Deneb about 50 degrees. Would fit as a quadrant, but is very early. The fisheye flattens objects near the horizon: Deneb is pictured at 24 degrees, although it appears to be close to the horizon. North is on the right.

Thanks for the data, so not the early quadrantide but the late Coma Berenicidi (or sporadic).
This must have been quite far in the north, when it was seen in almost the same direction both here and in Tampere.
The altitude here was about 40 degrees, so flew somewhere in the direction of Kemi?
Is it the case that faster meteors on average burn to completion at a higher rate if the size and composition are the same?

From the first video, the time code had dropped somewhere.

Kiimingin (79888) ja Tamperereen (79901) havaintojen keskinäisellä leikkauksella radiantti näyttäisi tarkentuvan melko hyvin Comae Berenicids (020-COM) tähdenlentoparveen, osuen noin 6 asteen päähän laskennallisesta radinatista ko päivälle.

Tåmå on todellakin lentänyt Kemin suunnalla. Kulkusuunta on noin 260 (länteen) sammumispisteen ollessa noin 30 km luoteeseen  Kemistä 80 km korkeudella. Voidaan tosiaan ajatella, että nopeammat meteorit palavat hitaampia aikaisemmin ilmakehässä. Tämäkin nopea syttyi näkyville jo lähes 120 km korkeudella.
