I’m and Michael Schwartz confirmed new SNe in the NGC 4051 spiral galaxy. This SNe discovered by Byelorussian astronomy amateur Vitaliy Nevskiy. Spectroscopic analisys on Dominion Astrophysical Observatory, shows the spectrum to be similar to that of a type-Ib/c supernova.  Comparison with a library of supernova spectra using the “superfit” matching program indicates that SN2010br is similar to the type-Ib/c supernova SN1987K. This supernovas practically haven’t hydrogen lines in the spectrum and progenitors of this SNe is very old and massive stars. On the discovery moment, the SN2010br have magnitude about R = 17.1m и V = 17.7m.
