Trajectory and orbit of the unique carbonaceous meteorite Flensburg

The C1-ungrouped carbonaceous chondrite Flensburg fell in Germany on September 12, 2019, the daytime. We determined atmospheric trajectory, velocity, and heliocentric orbit using one dedicated AllSky6 meteor camera three casual video records of bolide. It was found that meteorite originated vicinity 5:2 resonance with Jupiter at distance 2.82 AU. When combined bolide energy reported by U.S. Government sensors (USGS), pre-atmospheric diameter meteoroid estimated to 2 - 3 meters mass 10,000 20,000 kg. fragmented heavily atmosphere heights 46 37 km, under dynamic pressures 0.7 MPa. recovery just suggests only a very small part original reached ground. velocity vector compared USGS. There is good agreement radiant but value has been underestimated USGS almost 1 km/s.
