Discovery:  CBET 3264

 Richard Wainscoat and Marco Micheli, University of Hawaii, report the discovery of a comet in three w-band exposures taken with the 1.8-m Pan-STARRS1 telescope at Haleakala on 2012 October 17.39, noting the object to appear slightly extended relative to adjacent field stars. Micheli and Wainscoat later obtained three follow-up 120-s r-band exposures on Oct. 19 using the Canada-France-Hawaii Telescope (queue observer Lisa Wells), in which the object was seen to be clearly extended, but circularly symmetric with no sign of a tail (FWHM of the comet measured to be approximately 1".1, while that of adjacent stars was measured to be 0".75); at the time of the observation, the object moved across a very faint background galaxy, though it is not believed that the background galaxy contributed significantly to the extension of the point-spread function PSF of the comet.
