Comet P/2017 O2 = P/2010 D1 (Wise)
Abstract
E. Lilly and R. Weryk, Institute for Astronomy, University of Hawaii, reported the discovery of a comet on three w-band CCD images taken on July 30 with the 1.8-m Pan-STARRS1 telescope at Haleakala (discovery astrometry tabulated below); the object had an extended appearance, with full-width-at- half-maximum of approximately 1".4, compared to adjacent stars that had FWHM = 1".0, and there is some evidence for a faint tail extending for 10" towards p.a. 250 degrees. 2017 UT R.A. (2000) Decl. Mag. July 30.54206 0 42 00.18 + 1 58 12.8 21.1 30.55199 0 42 00.43 + 1 58 12.0 20.9 30.56192 0 42 00.67 + 1 58 11.4 21.0 M. Micheli writes that three follow-up 60-s CCD exposures were taken by R. J. Wainscoat and C. Wipper with the 3.6-m Canada-France-Hawaii Telescope (+ gri filters) at Mauna Kea on Aug. 1.47 UT, which show the object to be clearly cometary with a tail about 10" long in p.a. 250 deg; they measured g-band magnitude 20.5-20.7.
