SUPERNOVA IN ANONYMOUS GALAXY
     J. Maza, Department of Astronomy, University of Chile, telexes
that L. E. Gonzalez has discovered a supernova in a faint, anonymous
spiral galaxy at R. A. 22h56m.2, Decl. -40o53' (equinox. 1950.0).
The object is 7" east and 5" north of the galaxy's nucleus and on
May 30 was of photographic magnitude 18.


1982 HR
     The following ephemeris continuation is from improved orbital
elements given on MPC 6952 (1982 June 6).  The magnitudes have been
adjusted in light of recent observations.

1982 DA
     Further observations indicate that the ephemeris on IAUC 3680
is running off.  The following ephemeris continuation is from the
improved orbit on MPC 6952:
