A fireball at night, brigter than the venus - 7.3.2018 at 04.37 Helsinki Observation number 71415

Visibility III / V

Esko Lyytinen, Ursa (Etelä-Suomi)

I got a fireball camera, I didn’t see the fireball myself.

There are as many as 7 or 8 cameras known to show up.

Quickly, the observations of my own and Mikkeli's camera combined, says that it came in a northerly direction, flying at a slope of almost 60 degrees. I fly somewhat directly over Pori.

And the entry speed was about 30 km / s, which means that it mostly burned off at that speed, turning off at about 30 km (Mikkeli camera). So it wasn't a decent meteorite dropper, but something a little "crumb" must have come down.
