SUPERNOVA 2008cl IN UGC 10261
     J. M. Silverman, X. Wang, N. Lee, and A. V. Filippenko, University of
California, Berkeley, report that inspection of a CCD spectrum (range 340-1020
nm), obtained on May 17 UT with the Shane 3-m reflector (+ Kast spectrograph)
at Lick Observatory, shows that 2008cl (CBET 1378) is a type-Ia supernova
less than 1 week past maximum brightness.  Removing a host-galaxy recession
velocity of 19017 km/s (Kochanek et al. 2001, Ap.J. 560, 566), the minimum of
the Si II 635.5-nm absorption feature is found to be blueshifted by about
11000 km/s.
