Supernovae 2010gc, 2010gh, and 2010gp.
FOLATELLI G., GUTIERREZ C. and PIGNATA G.
Abstract (from CDS):
SN 2010gh is a type-II-P supernova between 20 and 30 days after the explosion. SNID provides a good match with the spectrum of SN 2004et at 28 days after the explosion. Assuming a recession velocity of 4714 km/s for the host galaxy (IC 4523; Peterson 1986, PASP 98, 1273), H-alpha is measured to be blueshifted by roughly 8000 km/s.
SN 2010gp is a type-Ia supernova with high expansion velocity around maximum light. SNID provides good matches to SN 2002bo and to SN 1981B just before maximum light. Adoping the recession velocity of 7339 km/s for the host galaxy (NGC 6240; Downes et al. 1993, Ap.J. 414, L13), the Si II 635.5-nm line apears blueshifted by about 14000 km/s.
