2018fpb, Type II in KUG 2357+340
Discovered 2018-08-31.540 by All Sky Automated Survey for SuperNovae (ASAS-SN), mag 16.8 at discovery
R.A. = 23h59m42s.802, Decl. = +34°20’39”.91

Observer: Cedric Raguenaud, SW France, GSNST
2018-09-15.149
Approx mag 15.56CV ±0.01, ZP=29.051mag
Note: it is difficult to distinguish core glow from supernova. Galaxy core is mag 15.0Bband according to SIMBAD. The maximum brightness is excentered and probably overlaps with supernova.
