Months of monsoon weather finally cleared this early morning to permit my first image of Comet ISON since April when it had just entered the orbit of Jupiter at a distance of 5 AU. The comet is now much closer and nearing the orbit of Mars approximately 1.6 AU from the Sun. I believe ISON promises to become a great comet by December. It has brightened considerably and its tail has grown much longer and more distinct since last April. The magnitude 15.1 galaxy to the lower right is NGC 2949.
