Comet 103P/ Hartley 2
Observations in South Bavaria / Germany (10/03 - 10/13/2010)

The periodical comet 103P/Hartley2 approached near to earth with an approx. brighness of mag*5,3 at the 10/20/2010 with 0,12 AE (18 Mio Km). Malcolm Hartley (Australia) discovered 1986 this unknown periodical comet. By an orbiting time of 6,27 years around the sun the comet was observed 1991/1997/2004 several times, but didn't reached the magnitude more than 8. In October 2010 a new occasion was given to the astronomers. So I tried to catch this poisson looking space gost on my own. Bad weather conditions in autumn made the observations a little difficult.

The comet is passing the Persues Double Cluster.

Up to mag +3-4 stars are visible nearby cities with the naked eye, in very dark areas the seeing limit can reach up to mag +6-7.
*mag = > light magnitude:
The more higher numerical value is given, the more weaker are the objects. E.g. - 4,7 mag, Venus glittering; - 1,0 Sirius, brightest star; +3,5 M31 Andromeda, pale shiny oval)
