Comments: Two sketches of 46P/Wirtanen plus one gif showing movement over time. 20:40 UT Dec 9th 2018 & 00:50 UT Dec 10th 2018. Inbetween haze and misty rain with some clear patches.
4.5 mag, DC 4 coma visible naked eye also, huge diffuse object. Thought I observed some radial features but not clear enough to include in the sketches. The edges/shape of the coma was difficult to see clearly. No green observed. No tail observed. I feel lucky to have seen it.
I have rotated the gif so as to have the upward movement of the comet right as my dob has south up.

Go Observe - 46P/ Wirtanen Good Luck
