SUPERNOVA 2008gp IN MCG +00-9-74
     P. Garnavich, University of Notre Dame, reports that a spectrogram
(range 340-800 nm; resolution 0.87 nm) of 2008gp (cf. CBET 1555) was obtained
with the Apache Point 3.5-m telescope (+ Dual Imaging Spectrograph) on Oct.
30.3 UT.  The spectrum shows a blue continuum with broad, deep features of Si
II and Ca II, consistent with a young type-Ia supernova.  The center of the
host galaxy also fell on the slit, and a redshift of z = 0.034 is found from
Balmer absorption lines and narrow emission features.  Correcting for this
recession velocity, the minimum flux of the Si II absoption has a blue-shifted
velocity of 12000 km/s.
