Conditions for viewing the comet were much better tonight. Little wind, and improved transparency. As a result, the comet was easier to spot. It was still very soft, but its apparent diameter was closer to 11 arc minutes (compared to 7 arc minutes visible last night). The central condensation was a bit more noticeable as well. Still no suggestion of elongation or a tail. It still fit in the same low power view as V Hydrae, although it was not as nicely placed as the night before. The comet had moved about 50 arc minutes west-southwest since my earlier observation 24.25 hours ago.
