SUPERNOVAE 2003gi AND 2003gj
     Additional apparent supernovae found on unfiltered CCD images
have been reported by L. A. G. Monard (SN 2003gi; cf. IAUC 8159)
and by M. Moore and W. Li (SN 2003gj; LOTOSS/KAIT; cf. IAUC 8158):

SN      2003 UT       R.A.  (2000.0)  Decl.   Mag.     Offset
2003gi  May 17.108   0 38 32.67  -24 20 33.5  15.6  1" E, 9" S
2003gj  June 30.4   21 07 19.18  -25 29 23.6  17.7  14".5 W, 8".9 S

Additional approximate magnitudes from the respective observers:
SN 2003gi in IC 1561, Apr. 29.134 UT, [18.0; July 1.103, 16.2.
SN 2003gj in NGC 7017, June 3.4, [18.5; July 1.4, 17.6.  Nothing is
present at the location of SN 2003gi on the Digitized Sky Survey
(limiting red mag 19).  The offset for SN 2003gj is with respect to
the western component of the interacting galaxy pair NGC 7017.

     K. S. Kawabata, Y. Ohyama, and the FOCAS team, National
Astronomical Observatory of Japan; K. Nomoto, University of Tokyo;
P. Mazzali, Trieste Observatory; and L. Wang, Lawrence Berkeley
National Laboratory, write:  "We obtained optical
spectropolarimetry (range 380-1020 nm) of SN 2002ic (cf. IAUC 8028,
8151, 8157) with the Subaru 8.2-m telescope (+ FOCAS) on June 27.6
UT.  SN 2002ic is still bright (R about 19) and still shows a
strong H_alpha emission line (FWHM about 6 nm) and a weaker H_beta
emission line (H_alpha/H_beta flux ratio about 16).  A broad and
strong Ca II triplet emission is also seen.  The spectrum has an
apparent similarity to that of the peculiar type-IIn supernova
1997cy between about 100 and 250 days after the explosion (Turatto
et al. 2000, Ap.J. 534, L57), and this is consistent with the
metamorphosis observed in the earlier phase (IAUC 8151).  The
depolarization across the H_alpha emission is distinct, which
indicates that SN 2002ic has a considerable intrinsic polarization
(p > 1 percent) at some wavelength regions.  The spectrum of SN
2002ic is dominated by the interaction region and appears similar
to a type-IIn supernova spectrum."
