Komet 103P/ Hartley2

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.

*mag  = > light magnitude. Up to apprx. mag 4-5 stars are visible  in the city with the naked eye, in very dark areas to mag 6. --> The more high numerical value is given, the more weak are the objects.
