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

This is an old observation of a fireball camera in the Haapamäki - Kärsämäki region, apparently from a fine fireball that dropped a few kilo-scale meteorite fragment, which was obtained in several fireball cameras. The image also shows the lattice spectra of the fireball on the sites. And I also put a graph on the spectrum. In it, the more easily identifiable emission spectral lines are the Na line just below 600 nm and the Mg line at about 518 nm. Otherly interfering with each other, there are apparently O-, Fe, and Ca spectral defects. Probably one of the few supposed meteorite dropers for which spectrum exists. May I still find that meteorite :)

The slight angle of entry makes it difficult to assess the location of the fall and also the fact that it broke into pieces.

The brightness rating -10 is here from Hesa. The closer was naturally brighter.
