SUPERNOVA 2007is IN UGC 10553
     J. M. Silverman, M. Ganeshalingam, and A. V. Filippenko, University of
California, Berkeley, report that inspection of CCD spectra (range 330-1030
nm), obtained on Sept. 19 UT with the Shane 3-m reflector (+ Kast
spectrograph) at Lick Observatory, shows that 2007is (CBET 1067) is a normal
type-Ia supernova near maximum brightness.  Removing the host-galaxy
recession velocity of 8897 km/s (from the Sloan Digital Sky Survey Data
Release 1), the minimum of the Si II 635.5-nm absorption feature is found to
be blueshifted by about 11600 km/s.
