SUPERNOVA 1996L IN ESO 266-G10
     R. H. McNaught, Anglo-Australian Observatory, reports his
discovery of a supernova (mag about 18.5), found on a U.K. Schmidt
telescope R plate taken on Mar. 19.6 UT by K. S. Russell and J. M.
James.  SN 1996L is located 20".5 east and 2".2 north of the center
of the host galaxy, at R.A. = 11h38m37s.80, Decl. = -43o25'13".8
(equinox 2000.0; uncertainty 0".5 in each coordinate).  A nearby
star of mag about 17.5 has position end figures 37s.90, 6".1.  No
image appears at the position of SN 1996L on several surveys of
various colors, the latest being in 1991.
     S. Benetti, European Southern Observatory (ESO); P. Barthel,
Kapteyn Astronomical Institute, Groningen; and W. de Vries, Space
Telescope Science Institute, write:  "Inspection of a preliminarily-
reduced CCD spectrum (range 375.7-695.2 nm, resolution 1.5 nm)
obtained on Mar. 21.15 UT with the ESO 3.6-m telescope (+ EFOSC1),
confirms this object as a type-II peculiar supernova (IIn).  Strong
H-delta, H-gamma, H-beta, and H-alpha emission lines are
superimposed on a blue continuum (black-body temperature about
11 500 K).  The Balmer lines show a complex structure consisting of
a narrow emission (FWHM about 900 km/s), on top of a broader one
(FWHM about 4300 km/s).  The He I (587.6 nm) line is also present
in emission, with a FWHM of about 2000 km/s.  The recession
velocity of the parent galaxy, as measured from emission lines of an
H II region west of the supernova, is 9900 km/s."
