POSSIBLE COMET WEST
     Richard M. West, European Southern Observatory, Geneva, telexes
that he has found another diffuse trail on a 60-min exposure
with the 100-cm Schmidt telescope at La Silla.  The motion is
unambiguous because images do not appear on partly overlapping plates
taken east of the position one and three days earlier.  Positions
of the beginning and end of the trail are:
