Astrometry using 118 USNO B1.0 stars and Astrometrica gives the following position: RA = 10h 44m 49.963s +/- 0.026s Dec = +21d 31' 18.16" +/- 0.34" Mag = 20.40 R +/- 0.21 An earlier image secured on April 21.91UT gave the R magnitude as 20.27 +/-0.38. SUPERNOVAE 2003dc, 2003dd, 2003de Further NEAT supernovae have been reported (IAUC 8111) as follows: 2003dc Mar 26.46UT RA 13h 54m 21.70s DEC +05 46' 09.3" (2000) Magnitude 19.3, offsets 1.2"E, 1.5"S 2003dd Mar 26.49UT RA 13h 56m 55.04s DEC +03 55' 58.2" (2000) Magnitude 20.1, offsets 14"E, 3"S 2003de Apr. 1.14UT RA 10h 10m 41.25s DEC +35 44' 52.9" (2000) Magnitude 17.2, offsets 1.7"W, 4.5"N SUPERNOVA 2003df IN ANONYMOUS GALAXY A further NEAT discovery has been reported on IAUC 8112. This object, of magnitude 20.3, was first recorded on Mar 9.47UT at: RA 12h 07m 31.36s DEC +26 57' 36.2" (2000), 2"W and 8"N of the centre of an anonymous galaxy. SUPERNOVA 2003cr IN UGC 9639 R. J. Foley et. al., University of California, Berkeley reports that a spectrum of this object found by Tom Boles (cf TA E-Circular 1874) was obtained on Apr 8 with the 3-m telescope at Lick Observatory. It shows a probable type Ic, a few weeks past maximum. SUPERNOVA 2003da IN UGC 4992 A spectrum of this object found by Tom Boles (cf TA E-Circular 1877) was also obtained showing it to be of type II shortly after maximum according to IAUC 8111. SUPERNOVA 2003db IN MCG +05-23-21 A spectrum of this object also found by Tom Boles (cf TA E-Circular 1878) shows it to be of type II a few weeks after maximum (IAUC 8111). Michael Schwartz advises that there was an independent LOTOSS detection of this object on a Tenagra image of Apr 7.4UT at magnitude 18.1. Guy M Hurst
