COMET P/2013 A2 (SCOTTI)
J. V. Scotti, Lunar and Planetary Laboratory, reports his discovery of a
diffuse comet with a short tail extending toward the northwest on CCD mosaic
images obtained with the Spacewatch 0.9-m f/3 reflector at Kitt Peak
(discovery astrometry tabulated below). Scotti's follow-up CCD images (27
stacked frames) taken with the Spacewatch 1.8-m f/2.7 reflector on Jan. 6.4 UT
show a 5" coma and a tail extending 0'.48 in p.a. 294 deg. After posting on
the Minor Planet Center's NEOCP webpage, N. Howes, E. Guido, and P. Phelps
write that six stacked 60-s R-band exposures taken with the 2.0-m "Faulkes
Telescope North" at Haleakala on Jan. 8.6 show the object to appear soft when
compared to nearby field stars of similar brightness, with an elongation
toward p.a. 220 deg.
