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). SN 2003 UT R.A. (2000.0) Decl. Mag.

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. 2002 UT R.A. (2000) Decl. Nov. 19.696 15 27.1 -23 28 (C) Copyright 2003 CBAT 2003 March 31 (8103) Daniel W. E. Green
