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.


SUPERNOVAE 2004D, 2004E, AND 2004F
     B. Swift, J. Burket, H. Pugh, R. J. Foley, A. V. Filippenko,
and W. Li report the LOSS discovery of three additional supernovae
on KAIT images.

SN      2004 UT        R.A.  (2000.0)  Decl.   Mag.     Offset
2004D   Jan.  4.5    11 56 27.82  +39 44 16.7  19.1   4".7 W, 14".1 S
2004E   Jan. 15.5    13 16 51.40  +31 35 11.8  16.1   3".2 E, 20".4 N
2004F   Jan. 16.2     3 17 53.80  - 7 17 43.0  17.8   6".0 E, 9".2 N

Additional KAIT magnitudes:  SN 2004D in UGC 6916, 2003 May 22.3 UT,
[19.5; 2004 Jan. 10.5, 19.0.  SN 2004E in PGC 46239, 2002 Dec. 25.1,
[19.5; 2004 Jan. 16.5, 16.1.  SN 2004F in NGC 1285, 2003 Nov. 21.2,
[18.5; 2004 Jan. 17.2, 17.9.  Foley, Serduke, Chornock, and
Filippenko add that inspection of CCD spectra, obtained as above on
Jan. 17, reveals that SN 2004D is of type II, several months past
maximum brightness; relatively narrow H_alpha emission is dominant,
and the Ca II near-infrared triplet emission is also visible, but
[O I] and [Ca II] are weak or nonexistent, so the object has not
yet reached the nebular phase.  SN 2004E is of type Ia, with a
spectral-feature age (Riess et al. 1997, A.J. 114, 722) of 2 +/- 2
days past maximum brightness.
