SUPERNOVA IN ANONYMOUS GALAXY
     J. Maza, Department of Astronomy, University of Chile, reports
his discovery of a supernova on a plate taken by C. Torres of an
anonymous galaxy at R.A. = 13h31m.2, Decl. = -33o15' (equinox 1950.0). The
object is located 5" west and 5" north of the nucleus of the galaxy
and on June 13.118 UT was of photographic magnitude 18.
