C/2025 F2 ( SWAN ) Bright new comet discovered in the SWAN images. It brightened rapidly up to 7.8 mag on Apr. 8 (Osamu Miyazaki). Then it has been fading before the perihelion passage. Now it is 9.4 mag (Apr. 15, Mike Olason). In the Northern Hemisphere, it will be unobservable in May. In the Southern Hemisphere, it is not observable now, but it will appear in May. Date(TT) R.A.
