A fireball at night, as bright as a cresent moon - 1.11.2019 at 03.38 Helsinki Observation number 86306

Visibility IV / V

Esko Lyytinen, Ursa (Etelä-Suomi)

There is a fireball camera detection with an infrared camera.

The picture on the right shows almost only a flash. Yes, the movement survived the detection and the duration was 0.56 s.

At the edge of the image, the bright mark has spread asymmetrically.

I estimate that there was about a mag -9 brightness seen here, in which case the absolute brightness (100 km away) would have been about the full moon brightness. Quickly burned out.
