Observation: 2018fpb (bis)

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
2018-10-05.861
Approx mag 15.94CV ±0.01, ZP=29.326mag
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. The reported magnutude is low confidence.
