First return of a new bright periodic comet. It was observed as an asteroid in June. Now it is 17.3 mag by CCD observations (Aug. 3, Siding Spring Survey). However, because it looks very diffuse, the total magnitude can be around 14-15 mag. The condition in this apparition is very good. The comet will pass near by the earth and is expected to reach up to 13-14 mag. Now it locates very low in the Northern Hemisphere, but it keeps observable high until early August in the Southern Hemisphere. It is not observable in latter half of August. In the Northern Hemisphere, it appears in the morning sky at 15 mag in late August, then it keeps observable in a good condition. Maybe it becomes visible visually.
