* C/2016 R3 ( Borisov )

It will approach to the Sun down to 0.45 a.u. on Oct. 10. But it is not observable now. It was 12.5-13.0 mag on Sept. 24 (Michael Jager). It will never be observable again in the Northern Hemisphere. In the Southern Hemisphere, 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 ).
