Comment | Good, clear skies here last night, and I was able to grab one more observation of 209P. It was pretty low in my southern sky, at a declination of –40 degrees. There is still a pretty strong central condensation, but the rest of the coma seems a bit more prominent relative to that compared to what it has been; I'd put DC ~6-7. |
