  On February 6, 2016 at 21:07:19 UT, a very bright fireball was seen over the
eastern part of Denmark. The weather was cloudy over eastern Denmark, but many
people saw the sky light up-even in the heavily illuminated Copenhagen. Two
hundred and thirty three reports of the associated sound and light phenomena
were received by the Danish fireball network. We have formed a consortium to
describe the meteorite and the circumstances of the fall and the results are
presented in this paper. The first fragment of the meteorite was found the day
after the fall, and in the following weeks, a total of 11 fragments with a
total weight of 8982 g were found. The meteorite is an unbrecciated, weakly
shocked (S2), ordinary H chondrite of petrologic type 5/6 (Bouvier et al.
2017). The concentration of the cosmogenic radionuclides suggests that the
preatmospheric radius was rather small ~20 cm. The cosmic ray exposure age of
Ejby (83 +/- 11 Ma) is the highest of an H chondrite and the second highest age
for an ordinary chondrite. Using the preatmospheric orbit of the Ejby meteoroid
(Spurny et al. 2017) locations of the recovered fragments, and wind data from
the date of the fall, we have modeled the dark flight (below 18 km) of the
fragments. The recovery location of the largest fragment can only be explained
if aerodynamic effects during the dark flight phase are included. The recovery
location of all other fragments are consistent with the dark flight modeling.
