Description

The comet Garradd late October 2011, with an orbit of unfavorable geometry temporarily away from Earth as it continues its approach to the Sun, despite its great absolute brightness it allowed to continue increasing its visual magnitude slowly until the 7.5 when I got this picture. This geometry also makes us see the tail at an closed angle, extending behind him and slightly to the right, as shown in the picture.
