The object, of B about 16.5 was located: RA 02h55m48.63s DEC -05 01'08.0" (1950) 9.4"E and 4.4"S of the nucleus. IAUC 4591 SUPERNOVA 1988M IN NGC 4496B A.V.Filippenko, University of California at Berkeley et al report the discovery of a probable type II supernova long past maximum brightness in NGC 4496B which is located: RA 12h 29.1m DEC +04 12.1', (1950) The object was recorded in a long-slit spectrum of Apr 7 (pa 180 degrees, range 620-686 nm, resolution 0.2-0.3 nm). Weak, broad H-alpha emission was detected 12.5" south of the nucleus. Comparison with SN 1980K suggests that SN1988M is probably 300-400d past maximum. Could observers please check their files/photographs obtained over the last 2 years for evidence of this object.
