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