* C/2016 R3 ( Borisov )

New comet. Now it is bright as 12.9 mag (Sept. 14, Alan Hale). It will approach to the Sun down to 0.45 a.u. on Oct. 10. In the Northern Hemisphere, it will be unobservable in late September, then it will never be observable again. In the Southern Hemisphere, it is not observable now. It will appear in the evening sky at 14 mag in November, but it keeps extremely low after that. It has a very similar orbit to Comet C/1915 R1 ( Mellish ). Hidetaka Sato reported it faded down to 17.7 mag on Sept. 16.
