COMET AUSTIN (1989c1)
Rodney R. D. Austin reports his discovery of a comet. The following
positions are available:
     1989 UT             R.A. (1950) Decl.       m1     Observer   
     Dec.  6.6        0 48         -62           11     Austin

R. R. D. Austin (New Plymouth, New Zealand).  Comet diffuse.
P. V. Birch (Perth).  Comet diffuse without condensation.
                                                     IAUC 4919
ASTEROID 9 (Manning)
Brian Manning, Stakenbridge, reports his discovery of a further
asteroid (the ninth in the series):
1989 Nov 22.87211 02h50m42.70s +12 57 51.5
         22.89446 02 50 41.57  +12 57 51.9
         23.93765 02 49 49.28  +12 58 13.3
         25.86156 02 48 15.59  +12 59 01.8
Brian Marsden advises us that this object is to be designated
1989 WN1 and may be an Eos family member.
With regard to object 8 (cf E359), Brian Marsden has named this
1989 VX and suggests it is identical with 1978 UE4 although the
1989 discovery is the principal one. More detailed information
will appear in TA in due course,
