SUPERNOVA 2003ls NEAR PGC 11402

Further to IAUC 8266, R. J. Foley and A. V. Filippenko,
University of California at Berkeley (UCB), report the LOSS
discovery, on KAIT images taken on 2003 Dec. 22.3 (mag about 16.5)
and 28.2 UT (mag about 17.0), of an apparent supernova located at
R.A. = 3h01m00s.39, Decl. = -10o53'04".5 (equinox 2000.0; revision
to position given on CBET 58), which is 170" west and 55" north of
the nucleus of PGC 11402.  A KAIT image taken on Nov. 25.3 showed
nothing at this position (limiting mag about 19.0).  Foley, F. J. D.
Serduke (Lawrence Livermore National Laboratory), R. Chornock (UCB),
and Filippenko report that inspection of CCD spectra (range 330-
1000 nm), obtained on 2004 Jan. 17 with the Shane 3-m telescope at
Lick Observatory, reveals that the new object is of type Ia, about
1.5 months past maximum brightness.  Its redshift, estimated by
comparing the spectrum with that of other type-Ia supernovae, is
about 13000 km/s -- much greater than that of PGC 11402 (9276 km/s,
from NED), so it must be in a faint background galaxy unrelated to
PGC 11402.
