Searching supernovae around the universe
2018huy. Type Ia in unknown galaxy
Discovered 2018-11-01.516 by ZTF, mag 18.79 at discovery
R.A. = 08h32m44s.010, Decl. = +31°11’00”.49
Observer: Cedric Raguenaud, SW France, GSNST
2018-11-19.052
Approx mag 19.36CV ±0.11, ZP=29.473mag
Note: it is difficult to distinguish host galaxy core from supernova.
0.25m/f4 reflector + CCMOS, 0.5″/pixel

Previous observation on 2018-11-11.017 reported mag 18.01CV.
2018iko, Type Ia in 2MASX J07563416+3010325
Discovered 2018-11-07.375 by ZTF, mag 18.42 at discovery
R.A. = 07h56m34s.150, Decl. = +30°10’35”.82
Observer: Cedric Raguenaud, SW France, GSNST
20181119.090
Approx mag 17.20CV ±0.01, ZP=29.567mag
Note: the SN is very close to the galaxy core, therefore photometry is unreliable
