There was a fireball camera sighting, 3 minutes from the previous one.

The automatic detection had a duration of 3.68 s.

A rough estimate of the entry speed is of the order of 20 km / s. May have dropped a small meteorite, tens of grams perhaps.

Extinguished in direction 344.4, at an elevation angle of 15.6 degrees.
