December 22, 2017

 
 This
            comet has been very active lately, currrently around 11th magnitude
            it has displayed puffs of gas, rays in the coma and parabolic
            envelopes near the central regions and tail. Tonight only a few
            rays coming from the coma, but a very nice rich blue color.
