78391 Michaeljäger           Discovered 2002 Aug. 8 by S. F. Hönig at Palomar.
Michael Jäger (b. 1958) is one of the most prolific and recognized comet astrophotographers. Within the last decades he imaged around 300 different comets and discovered comet P/1998 U3 as well as fragment D of comet 141P/Machholz. In 2002 he assisted the discoverer with confirmation of comet C/2002 O4 (Hönig).
