SUPERNOVA 1996A IN ANONYMOUS GALAXY
     B. P. Schmidt, Mount Stromlo and Siding Spring Observatories,
reports the discovery of a supernova by R. O. Evans on a U.K.
Schmidt R film taken by P. Cass on Jan. 12 as part of the
U.K. Schmidt Supernova Search.  SN 1996A, of mag about 18,
is located at R.A. = 5h10m47s.1, Decl. = -3d00'25" (equinox 2000.0),
in an anonymous galaxy.  It is offset 1" east and 4" south from a
mag 14 star located on top of the galaxy's nucleus.  It is not
visible on a similar film taken 1995 Dec. 12.

     M. M. Phillips and A. Clocchiatti, Cerro Tololo Interamerican
Observatory, report: "A fully-reduced spectrogram (range 350-720 nm,
resolution 0.4 nm) of SN 1996A, obtained on Jan 18.14 UT at the 4-m
Blanco telescope, shows the typical features of a type II supernova
approximately three weeks after maximum light.  H beta is blueshifted
by approximately 9000 km/s, and H alpha has a well-developed emission
and a weak absorption blueshifted by approximately 9500 km/s.  The
parent galaxy shows a redshift of 0.033, measured from emission in
H alpha and [N II] 6584 nm.  The supernova is offset by 9" in p.a.
approximately 140 deg from the bright star located on top of
the galaxy."
