SUPERNOVAE 2004ex AND 2004fc

      Further to IAUC 8412, K. Shimasaki and W. Li report the LOSS
discovery of an apparent supernova on unfiltered KAIT images taken
on Oct. 21.39 (mag about 15.5) and 22.40 UT (mag about 15.4).  SN
2004fc is located at R.A. = 1h51m03s.85, Decl. = -9o42'06".9
(equinox 2000.0), which is about 2" east and 2" north of the
diffuse nucleus of NGC 701.  A KAIT image taken on Oct. 14.39
(limiting mag about 19.0) showed nothing at this position.  H.
Yamaoka, Kyushu University, reports the following prediscovery
unfiltered CCD magnitudes of SN 2004fc by K. Itagaki (Teppo-cho,
Yamagata, Japan, 0.60-m reflector):  Oct. 16.624, 15.4; 17.577,
15.4; it was not detected on an image taken on Oct. 6.718 (limiting
magnitude difficult to estimate due to proximity to host-galaxy
nucleus).
     An independent discovery of SN 2004ex (cf. IAUC 8418, 8420)
was made by Shimasaki and Li, with the following approximate
unfiltered CCD magnitudes available:  Oct. 6.35, [20.0; 10.33,
[19.0; 14.33, 18.6.
