New bright comet discovered by three amateur comet hunters. Now it is 8.9 mag (Nov. 16, Katsumi Yoshimoto). It brightened rapidly from 10 mag up to 8 mag just after the discovery. But after that, the brightness evolution became slow. In the Northern Hemisphere, it is observable in the morning low sky until mid November. It can be observable in the extreme low sky until around Nov. 24. It can be observable in the extreme low sky in the evening at 5.5-7 mag from around Dec. 5 to around Dec. 15. In the Southern Hemisphere, it is not observable now. But it will appear in the morning sky at 14 mag in February, then it stays observable in good condition while the comet will be fading gradually.
