Abstract (from CDS):

Five apparent supernovae have been discovered on unfiltered CCD images: 2004el in MCG +09-25-4 by R. Arbour (cf. IAUC 8376), 2004em in IC 1303 by M. Armstrong (cf. IAUC 8399), 2004en by T. Boles (cf. IAUC 8405), 2004eo in NGC 6928 by K. Itagaki (cf. IAUC 8377; via S. Nakano), and 2004ep in IC 2152 by M. Moore and W. Li (LOSS/KAIT; cf. IAUC 8401). SN 2004 UT R.A. (2000.0) Decl. Mag.

Briggs (near Portsmouth, England) on Sept. 14.9 yielded position end figures 51s.84, 05".7. SN 2004el was also not present on the (Digitized Sky Survey) Palomar plates taken in 1991 (limiting blue mag 20.1) and 1994 (limiting red mag 19.8).
