* 46P/Wirtanen

Now it is very bright as 6.6 mag (Nov. 11, Chris Wyatt). It will approach to Earth down to 0.08 a.u. in December, and it is expected to brighten up to 3 mag. In the Northern Hemisphere, it locates low until November, but it stays observable in excellent condition after December. In the Southern Hemisphere, it is observable in good condition until mid December when it brightens up to 3 mag. But it becomes unobservable after that.

* C/2018 V1 ( Machholz-Fujikawa-Iwamoto )

New bright comet discovered by three amateur comet hunters. Now it is very bright as 7.5 mag (Nov. 11, Charles Morris). 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.
