SUPERNOVA 2004C IN NGC 3683
C. C. Dudley and J. Fischer of the Naval Research Laboratory have 
reported the detection of a mag K about 14 object in NGC 3683 on 2004 
Jan 12.5UT. The position of the source is:
RA 11h 27m 29.72s DEC +56 52'48.2" (2000), 17"W, 10"N of the nucleus of 
NGC 3683.

Tom Matheson et. al., have reported on IAUC 8269 that a spectrum 
obtained by P. Berlind on Jan. 15.5UT with the F. L. Whipple
Observatory 1.5-m telescope (+ FAST spectrograph), shows it to be a
type-Ic supernova.
