SUPERNOVAE 2004gn AND 2004go
Further to IAUC 8447, W. Li reports the LOSS discovery of an apparent supernova (mag about 16.6) on an unfiltered KAIT image taken on Dec. 1.57 UT. SN 2004gn is located at R.A. = 12h34m12s.10, Decl. = +2o39'34".4 (equinox 2000.0), which is 55".0 east and 21".4 north of the nucleus of NGC 4527. A KAIT image on June 10.21 showed nothing at this position (limiting mag about 19.0). H. Yamaoka, Kyushu University, reports that K. Itagaki, Yamagata, Japan, has confirmed the existence of the new object at red mag about 16.7 in unfiltered CCD images taken on Dec. 2.806 (the position end figures given as 12s.10, 34".7). H. Pugh and Li report the LOSS discovery of another apparent supernova on unfiltered KAIT images taken on Nov. 18.32 (at mag 16.5), 23.25 (mag 16.6), Dec. 4.32 (mag 17.3), and 5.29 UT (mag 17.3). SN 2004go is located at R.A. = 2h55m41s.76, Decl. = -14o14'14".5 (equinox 2000.0), which is 34".8 west and 105".7 south of the nucleus of IC 270. A KAIT image taken on Oct. 14.43 showed nothing at this position (limiting mag about 19.0).-----------------------------
