SUPERNOVA 1976O IN ESO 234-G16
R. H. McNaught, University of Adelaide, reports the discovery
of an apparent supernova of mag about 16 in ESO 234-G16 on a U.K.
Schmidt Telescope (UKST) J survey photograph taken 1976 Aug. 19.5
UT by M. Hartley. The supernova is located at R.A. = 20h19m44s.72,
Decl. = -50 42'10".1 (equinox 1950.0), offset 6".1 west and 13".7
north of the galaxy nucleus and situated in a spiral arm. Nothing
is present in the position of SN 1976O on a UKST J plate taken by
Hartley on 1990 July 25, nor on the ESO B survey film taken 1975
July 12. M. A. Read, Royal Observatory, Edinburgh, notes that
nothing appears to a limit of mag about 21 on UKST J plates taken
1976 May 31 and June 24.
