SUPERNOVA 2008as IN ESO 567-G57
     Further to CBET 1271, W. Li and A. V. Filippenko, University of California
at Berkeley, report the LOSS discovery of an apparent supernova on unfiltered
KAIT images:

SN       2008 UT        R.A. (2000.0) Decl.     Mag.     Offset
2008as   Feb. 29.38   10 21 47.89 -19 29 42.0   16.9   3".0 W, 0".6 S

Additional KAIT magnitudes for 2008as:  Jan. 15.42 UT, [18.5; Feb. 7.39, 16.2;
Feb. 17.42, 16.7.
     S. Blondin, Harvard-Smithsonian Center for Astrophysics (CfA), on behalf
of the CfA Supernova Group, reports that a spectrogram (range 400-1000 nm) of
2008as, obtained by P. Challis on Mar. 1.24 UT with the Magellan Clay 6.5-m
telescope (+ LDSS3), shows it to be a type-Ia supernova around one month past
maximum light.  Cross-correlation with a library of supernova spectra, using
the Supernova Identification code (SNID; Blondin and Tonry 2007, Ap.J. 666,
1024), indicates that 2008as is most similar to the type-Ia supernova 1996X
at 32 days past maximum.
