SUPERNOVA 2007iv IN UGC 12917
P. Garnavich and M. Russell, University of Notre Dame, report
that they obtained a spectrum of 2007iv (cf. CBET 1070) with the Kitt
Peak 4-m Mayall telescope (+ MARS spectrograph) on Sept. 18.2 UT.
The spectrum shows a broad P-Cyg profile of H-alpha and He I 587.5-nm,
suggesting that this is a type-II supernova. Narrow emission lines
from the host provide a redshift of 0.045.
