SUPERNOVAE 2003dc, 2003dd, 2003de
     Further to IAUC 8106, W. M. Wood-Vasey, G. Aldering, P. Nugent,
and S. Brar report apparent supernovae found on unfiltered NEAT
images:

SUPERNOVAE 2003cr, 2003da, AND 2003db
     R. J. Foley, M. Papenkova, D. Weisz, A. V. Filippenko, and R.
Chornock, University of California, Berkeley, report that
inspection of CCD spectra (range 310-1000 nm), obtained on Apr. 8
UT with the Shane 3-m telescope at Lick Observatory, reveals that
SN 2003cr (IAUC 8103) is probably of type Ic, within a few weeks
past maximum brightness.  SN 2003da (IAUC 8108) is of type II
shortly after the explosion; the very blue continuum is nearly
featureless, but low-contrast hydrogen Balmer lines and weak He I
587.6-nm are visible and have P-Cyg profiles.  SN 2003db (IAUC
8108) is also of type II, probably a few weeks after the explosion.
The broad H_alpha emission line is much stronger than the absorption
component.
     M. Schwartz and P. R. Holvorcem report the independent LOTOSS
(cf. IAUC 7906) discovery of SN 2003db on unfiltered Tenagra II CCD
images taken on Apr. 7.4 (at mag 18.1) and 8.2 UT (mag 17.9); the
new object was not present (to mag about 18.5) on an image taken on
Feb. 28.5.


COMET C/2002 W8 (SOHO)
     Further to IAUC 8106, D. Hammer reports measurements for a
Kreutz sungrazing comet found on C2 and C3 SOHO website images by
K. Cernis (not X.-M. Zhou, as stated on MPEC 2003-G32, where the
reduced astrometry and orbital elements appear).

     2002 UT           R.A. (2000) Decl.
