New Comet In Evening Sky!

New comet discovered by many people in the SWAN images released in late August. It has already passed the perihelion on Aug. 9, and it is fading now. But it is still bright as 9.5 mag visually (Aug. 25, Alan Hale). In the Northern Hemisphere, it keeps low in the evening until early September, then it will be higher in the morning sky after mid September. But it will be 13 mag in October. In the Northern Hemisphere, it must have been visible in good condition in the evening before the discovery, however, it is unobservable after this.
