COMET C/2011 Q1 (McNAUGHT)
R. H. McNaught reports his discovery of another comet on CCD images taken
with the 0.5-m Uppsala Schmidt telescope (discovery observation tabulated
below), the object showing a basically circular coma about 12" across,
possibly elongated toward the northwest with a suggestion of a tail about
0'.2 long toward the northwest; the comet is strongly condensed. After
posting on the Minor Planet Center's NEOCP webpage, P. Birtwhistle reported
a slightly cometary appearance, as well, from his images taken on
Sept. 5.1 UT with a 0.40-m f/6 Schmidt-Cassegrain reflector.
