SUPERNOVA 1992ad IN NGC 4411B
R. H. McNaught, Anglo-Australian Observatory, reports the discovery
on July 1.37 UT by R. Evans, Hazelbrook, N.S.W., of a supernova of
mv = 13.5 located about 40" east and 40" south of the centre of
NGC 4411B (R.A. = 12h24m.25, Decl. = +9 09'.7, 1950.0). Evans noted
the supernova's brightness as unchanged on July 2.4. McNaught
provides the following measurement of the supernova's position:
R.A. = 12h24m17s.04, Decl. = +9 09'14".2, uncertainty 0".4 in each
coordinate).  A nearby star of mag 13.0, on the opposite
(northwest) side of the galaxy, has end figures 10s.24, 10'24".4.
The galaxy is a face-on spiral of low surface brightness and does
not appear on the short exposure taken with the Uppsala Southern
Schmidt telescope on July 2.36.  However, offsets for the supernova
relative to the coordinates of the nucleus in the Hubble Guide Star
Catalogue are 34".6 east, 26".2 south.  Nothing appears in this
position on the first Palomar Sky Survey or in the NASA Atlas of
Galaxies.

J. Spyromilio, Anglo-Australian Observatory has since reported
spectral confirmation indicating it is a type-II supernova.

SUSSEX CLUSTER
The VAX service at Sussex Cluster is shortly to be shut down as a
new service is to be launched using UNIX.
With immediate effect please do not send any further messages to
GUYH at UK.AC.SUSSEX.CLUSTER but direct all mail to the existing
boxes at RLSAC and CAVAD.
