COMET C/2012 K4 = P/2005 N3 (LARSON)
N. Howes, G. Sostero, and E. Guido report their recovery of comet
P/2005 N3 (cf. IAUCs 8560, 8564) on stacked R-band CCD exposures (astrometry
tabulated below) taken remotely with the 2.0-m "Faulkes Telescope North" at
Haleakala. The comet has an ill-defined central condensation of magnitude
about 20.3 surrounded by a weak coma 5" in diameter, with a faint and broad
tail nearly 8" long toward the southwest.
