SUPERNOVA 1988Y IN ANONYMOUS GALAXY
     P. Wild, Astronomical Institute, Berne University, reports his
discovery of a supernova at R.A. = 2h42m27s.70, Decl. = -8 37'05".8
(equinox 1950.0), at the southern tip of an anonymous galaxy.  The
object was of mpv = 16.0 on Nov. 14.9 UT and about 17 on Dec. 3.8.


1988 XB
     Y. Oshima, Gekko Observatory, Shizuoka, reports his discovery of a
fast-moving asteroidal object, as follows:

     1988 UT             R.A. (1950) Decl.       Mag.
     Dec.  5.78264    7 50 46.52   +23 15 50.8   16.0

           6.75764    7 42 46.42   +23 55 49.9

     Computations by S. Nakano, Center for Astrophysics, indicate
that the object is of Apollo type.  The closest approach to the
earth was 0.09 AU around Nov. 20.
