SUPERNOVAE 2004gq AND 2004gr
Discoveries of two supernovae have been reported from unfiltered CCD images: SN 2004gq independently by H. Pugh and W. Li (LOSS/KAIT; cf. IAUC 8448) and by F. Manzini (Novara, Italy, 0.4-m telescope; Stazione Astronomica di Sozzago Supernova Search), and SN 2004gr by LOSS. SN 2004 UT R.A. (2000.0) Decl. Mag.
