R. H. McNaught, Siding Spring Observatory, reports that William
A. Bradfield, Dernancourt, near Adelaide, has discovered a comet,
described to be diffuse without condensation.  Confirmatory CCD
images were obtained (through cirrus clouds) by S. D. Ryder and
McNaught with the Siding Spring 1.0-m reflector, and the Feb. 2

COMPUTER PROBLEMS
Unfortunately the main TA computer is still away being repaired
but I am now able to use e-mail thanks to the loan of an
alternative Lap-Top and modem. Hopefully we shall resume normal
service shortly but there may still be delays in answering non-
urgent e-mail for the next few days,
