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. 2007 UT R.A.
