Now it is 6.4 mag (Oct. 12, Artyom Novichonok), much brighter than originally expected in the extremely low sky. It will approach down to 0.4 A.U. to the sun on Oct. 28, and it will reach to 4 mag in mid October. However, the condition in the Northern Hemisphere is very hard. It locates extremely low, slightly over the horizon, in the morning sky from late September to mid October, and in the evening sky from mid October to late October. Then it will never be observable again. In the Southern Hemisphere, it will appear in the evening sky at 4-5 mag in early November, then it keeps observable while fading gradually, although it will not locate very high.

New bright comet of 11.6 mag (Oct. 11, Katsumi Yoshimoto). It must have been locating observable and brightening gradually in the Northern Hemisphere for a while, but it was not discovered until early October. In the Northern Hemisphere, it will be getting lower and lower, then it will be unobservable in early November. In the Southern Hemisphere, it will be unobservable for 1 month after mid November, but it will be observable in good condition at 10 mag from mid December to February. In the Northern Hemisphere, it will appear in the evening sky at 12 mag in March, then it keeps observable while fading gradually until May.

It keeps observable in good condition in the morning sky while it brightens rapidly. It will reach to 13 mag in early December, and will be visible visually. However, it turns to fade out and move lower very rapidly after Dec. 10, and it will be unobservable within a few days. Then it will never be observable again. It locates somewhat low in the Southern Hemisphere.

Peculiar asteroid moving on a cometary orbit. It was asteroidal at 18 mag in late August. It will reach to 15 mag in February and March. In the Northern Hemisphere, it keeps observable until July when it becomes fainter than 18 mag. It may show a cometary activity after this, although the perihelion distance is somewhat large as 1.8 A.U.
