SUPERNOVA 2005ba IN NGC 3746
     R. J. Foley, M. Ganeshalingam, D. S. Wong, B. J. Swift, and
A. V. Filippenko, University of California, Berkeley, report that
inspection of CCD spectra (range 330-1000 nm), obtained Apr. 11 UT
with the Shane 3-m telescope at Lick Observatory, shows that SN
2005ba (IAUC 8503) is of type II, probably within 2-3 weeks after
the explosion.  The spectrum consists of a blue, relatively
featureless continuum with P-Cyg H lines.  Adopting the NED redshift
of 9022 km/s, the expansion velocity derived from the minimum of the
H_beta absorption line has a velocity of about 11000 km/s.
