Abstract (from CDS):

MASTER OT J120451.50+265946.6 (M12045), discovered by the MASTER Global Robotic Net, is a Type Ib supernova (SN) that exploded in NGC 4080. We present the BVRI photometric and spectroscopic observations up to ∼250 d since Bmax. At the time of discovery the SN was a few weeks past maximum light and our observations capture the linearly declining light-curve phase. M12045 declines faster as compared to SNe 1999dn and 2009jf at comparable epochs. Rigorous spectroscopic monitoring reveals that M12045 is a normal Type Ib SN. The analysis of the nebular phase spectra indicates that ∼0.90 M☉ of O is ejected in the explosion. The line ratio of [O I] and [Ca II] in the nebular phase supports a massive WR progenitor with main-sequence mass of ∼20 M☉.
