SUPERNOVA 2008ay IN UGC 8050
     J. M. Silverman, R. Chornock, D. Poznanski, T. N. Steele, and A. V.
Filippenko, University of California, Berkeley, report that inspection
of a low-quality (due to clouds) CCD spectrum (range 320-920 nm), obtained
on Apr. 28 UT with the Keck I 10-m telescope (+ LRIS), shows that 2008ay
(CBET 1292) is probably a type-Ib supernova.  However, H-alpha absorption
appears to be visible, suggesting that the classification may actually be
type IIb.  Weak Si II 635.5-nm absorption may also be present.
