A fireball at night, brigter than the venus - 10.5.2012 at 01.11 Helsinki, Pukinmäki Observation number 4549

Visibility III / V

Esko Lyytinen, Ursa (Helsinki)

I got a fireball camera. I attach a 2 minute "summary". The more accurate time was November 1, 18. The duration was about 4.5 seconds. I have tentatively connected Mikkeli to the camera observation. Came from the north with a steepness of about 30 degrees.

When I came strongly towards Mikkeli, I initially misinterpreted (on which my comment on the visual observation was based) that Mikkeli's picture would have gone from the bottom up. Turned out to be the wrong conclusion. As a result, it would appear that the correct entry speed was "only" of the order of 15 km / s. And the prospects for the meteorite to drop are better. Extinguished at 32 miles. The brightness estimate is for apparent brightness from here at a distance. On closer inspection, the brightness of the moon did.

There was also a very short northern lights eruption coming into the same sum picture. However, it started dimmer already in the previous sum picture, so it was not generated by a fireball. There is no trace in the following summary image.
