PROBABLE SUPERNOVA IN ANONYMOUS GALAXY
     J. Maza, Department of Astronomy, University of Chile, telexes
that M. Wischnjewsky has discovered a probable supernova in a faint,
anonymous spiral galaxy, near NGC 5253, at R. A. 13h36m.9, Decl. -31o
28' (equinox 1950.0).  The object is 1" north and 32" west of the galaxy's
nucleus, and on the plate taken on June 22 by L. E. Gonzalez
the object was of photographic magnitude 16.5.
