October 25, 10:23-10:28 pm, PDT. This sketch was through 12x60 binos, from my driveway in the middle of light-polluted San Francisco, surrounded by six streetlights. Seeing 5/10, Transparency 2/10. Though you can't compare directly, I also observed through the binos on November 3 and the diameter of the comet's coma viewed through the binos has pretty much doubled. The sketch was made with Staedtler sketch pencils and blending stump on Strathmore 400 series drawing paper. It was scanned and processed on a Macintosh using Pixelmator graphics software. This is the oddest comet I've yet observed; as others have mentioned, it looks like a pregnant planetary nebula.
