SUPERNOVA 1993aj IN ANONYMOUS GALAXY
Christian Pollas, Observatoire de la Cote d'Azur, reports his
discovery of an apparent supernova (V = 18.5) located at
R.A. = 12h01m47s.38, Decl. = -0 26'31".9 (equinox 1950.0), which is
3".6 west and 3".9 south of the host spiral galaxy (V about 17).
The object was found on two Technical Pan films (limiting mag about
20.5) taken 1993 Dec. 27.23 and 28.24 UT.  The object is only 1 mm
from the side of the field.  Nothing is visible on the POSS prints
down to mag 19.5-20.  A nearby star of mag about 16 is located at
R.A. = 12h01m42s.90, Decl. = -0 24'53".9.

M. Hamuy, Cerro Tololo Interamerican Observatory, reports
confirmation by J. Storm (European Southern Observatory) of the
presence of a new stellar object 4".2 west and 4".2 south of the
galaxy's centre, as observed in B, V, and I images obtained on 1993
Dec. 29.333 UT with the CTIO 0.9-m telescope.
