CommentI managed to spot this comet this morning visually. My sky conditions were not all that good; even when the somewhat thick cloud that was in that part of the sky cleared out, I had the impression that I was still looking through some very thin clouds, which became apparent after dawn had advanced. The comet appeared “soft,” vague, and diffuse. I detected clear and obvious motion over a half-hour interval.
