COMET BRADFIELD (1975d)
     Mr. William A. Bradfield, Dernancourt, near Adelaide, cables
that he has discovered a comet, as shown below.  Approximate positions
have also been reported by D. Herald (Woden, near Canberra)
and B. Tregaskis (Mount Eliza, Victoria).  Bradfield and Herald
describe the comet as diffuse, without condensation, while Tregaskis
noted some condensation.
