Comments
Mouse-over the image to see the labels. The observing condition was very poor at low elevations due to great humidity, although the Milky Way from Perseus to Auriga to Gemini was discernible by naked eye. At approximately the same elevation, I could only merely see Canopus by naked eye! No measurement was made owing to the poor SNR of the comet, which will result in great uncertainty.
