COMET C/2012 K6 (McNAUGHT)
     R. H. McNaught reports his discovery of a comet (discovery observations
tabulated below) on CCD images taken with the 0.5-m Uppsala Schmidt telescope
at Siding Spring.  Follow-up images taken by McNaught on May 29.8 UT show a
coma of diameter about 10", while further exposures on May 30.8 show the
comet extended to the northwest by a few arc seconds.
