Details:
The comet looked a bit smaller and darker at the night compared to two days before, though I could take more data than before. It may be partly due to the hazy sky at the night.
The comet was drifting fast toward west northwest in Ursa Major. Whitish coma got a bit smaller and darker compared to that 2 days before. Whitish tail got far longer toward southeast, the length around 26 arcminutes including a possible separated part. Bluish Green ion coma got a bit smaller around 24 arcminutes in diameter at the night. North is up, and east is to the left.
