SUPERNOVAE 2003cp, 2003cq, 2003cr, 2003cs, 2003ct
     Additional discoveries of apparent supernovae have been
reported from unfiltered CCD images -- SN 2003cp in MCG +10-12-78
by M. Armstrong (cf. IAUC 8074); SN 2003cq in NGC 3978 by R. Arbour
(cf. IAUC 8097); SN 2003cr in UGC 9639 by T. Boles (cf. IAUC 8093);
and SNe 2003cs and 2003ct by W. M. Wood-Vasey et al. (NEAT images;
cf. IAUC 8102).

Additional approximate CCD magnitudes (from the respective
discoverers unless noted otherwise):  SN 2003cp, 2000 Dec. 30 UT,
[19.0; 2003 Mar. 14, [18.5; 31.786, 16.2.  SN 2003cq, Mar. 14,
[17.4; 31.816, 17.9 (Boles); 31.830, 17.0.  SN 2003cr, Feb. 24,
[19.0; 31.894, 17.5.  SN 2003cs, 2002 Apr. 18.14, [20.8; 2003 Feb.
9.44, 17.1; Mar. 27.19, 19.4; 31.22, 19.6.  SN 2003ct, Feb. 9.44,
[20.6; Mar. 25.20, 19.1; 31.22, 19.1.  Nothing is visible at the
locations of SNe 2003cp, 2003cq, or 2003cr on Palomar Sky Survey
red or blue plates.  Arbour adds that a CCD image by D. Briggs on
Mar. 30.885 yields position end figures 14s.11, 19".3 for SN
2003cq, while Boles measured position end figures 14s.20, 19".6
from his own image taken on Mar. 31.816.


SUPERNOVA 2003bw IN IC 1077
     Further to IAUC 8102, M. Hamuy reports that a spectrum of SN
2003bw (cf. IAUC 8093), obtained on Mar. 31.39 UT, shows it to be a
type-II supernova, at least two months old.


COMET C/2002 W5 (SOHO)
     Further to IAUC 8100, D. Hammer reports measurements for a
Kreutz sungrazing comet found by S. Hoenig from SOHO C2 and C3
coronagraph website images.  The reduced astrometry and orbital
elements by B. G. Marsden appear on MPEC 2003-F45.
