A fireball at night, as bright as a cresent moon, Helsinki 72

There is a fireball camera, I did not see. It was the first of two fireballs of the night, the second one flying much closer came exactly 3 minutes later. This came so exactly in minute 02 that it split into two 2 minute totals. For that reason, I put a 10-minute picture that shows the whole (every fifth frame). Did the exchange of images just confuse the recognition as there was no automatic detection. Can measure manually, but I haven't had time to do it yet. I set the brightness rating to mag. -8, but there might have been close to the brightness of the full moon at close range.

The northern lights were just about to run out, meaning they waned quickly. Somewhat earlier, the sky in the picture would have been so saturated that it might have been completely invisible. Now you can see the northern lights mainly on the right side. And here are the visual observations. Suddenly, not everyone can say which fireball was involved.

So it’s low there in the tops of the trees, ending in a bright flash. The extent to which the image continued to flash "inside" remains unclear.

Mikko Huhdanmäki was lucky and saw both fireballs, ie two notable fireballs every three minutes: http://www.taivaanvahti.fi/observations/show/68140

Me näimme nuo molemmat tulipallot, piirsin niistä radat havaintoon, upeaa nähdä kamerakuvistasi samat. Tämä ensimmäinen ja matalammalla ollut sammui ennen horisonttia. Omat aikamääreeni voivat heittää minuutin kumpaan tahansa suuntaan, en katsonut sekunteja, kun en meinannut kipinöinnin vuoksi uskoa meteoriiteiksi ensinkään.

Oulussa saatu kuvaan ilmeisesti tämä bolidi. Se näkyi pilvisellä taivaalla ja alkoi 00:59:58. Tarkistan asian ja laitan kuvan vahtiin.

Tämäkin siis meni 8.11. puolella, vai ?

Kyllä meni 8. puolella. Sorry kun tuli taas töpättyä. Kun käytän itse UT aikaa ja siinä 7. puolella, niin kelloajan muutin, mutta unodin tuon päiväyksen.

Yritän korjata.
