COMET 2007 K5
     T. Lovejoy, Thornlands, Queensland, Australia, reports his
discovery of a comet on twelve 90-s CCD images obtained on May 26
with a 200-mm f/2.8 camera lens, the object reported as circular,
1' across, with a clear blue-green color but no tail.  J. Drummond
(Gisborne, New Zealand, 0.20-m f/4.6 reflector) writes that his
confirming images from May 28, obtained at altitude about 15 deg,
show a moderately condensed coma of diameter about 1' and no tail.
The following reported positions include precise astrometry by R. H.
McNaught from images obtained with the 0.5-m Uppsala Schmidt
telescope at Siding Spring, who reported a circular coma 0'.6 in
diameter.  Additional accurate astrometry is needed.
