SUPERNOVA 2007qe
     P. Garnavich, University of Notre Dame; H. Marion, University of Texas
and Texas State University; and P. Challis, S. Blondin, and R. Kirshner,
Harvard-Smithsonian Center for Astrophysics, report that they obtained
spectra of SN 2007qe (cf. CBET 1138, 1145) and its host galaxy using the MMT
(+ Blue Channel spectrograph) on Dec. 14.1 UT.  The spectrum of the host
galaxy shows weak H_alpha emission at 671.97 nm and Ca II H and K absorption
corresponding to z = 0.024.  This is more than twice the redshift derived
from the supernova spectrum (CBET 1138) and suggests a higher-than-typical
expansion velocity.  With this revised redshift, Garnavich et al. re-
interpret the IRTF near-infrared spectrum taken on Nov. 16.3 (CBET 1145) and
find a Ca II expansion velocity of 28500 +/- 1500 km/s.
