COMET P/2010 W1 (GIBBS)
A. R. Gibbs, Lunar and Planetary Laboratory, reports his discovery of
a comet (discovery observation tabulated below) on Catalina Sky Survey images
obtained with the 0.68-m Schmidt telescope; four co-added 20-s discovery
exposures show a "fuzzy" coma of diameter 8" (and magnitude 18.1-18.6) with no
visible tail (FWHM larger than nearby stars of similar magnitude). Four
additional co-added 60-s exposures by Gibbs from Nov. 27.25 UT show the coma
size as 11' x 8'.5, elongated in the direction of motion (p.a. 85 deg), again
with no visible tail.

This object was identified by T. B. Spahr on the Minor Planet Center's
"Daily Orbit Update" for Nov. 28 (MPEC 2010-W45) with the following objects
that had received minor-planet designations: 1996 TT65, 2010 MS75, 2010 RR59,
2010 RN141, 2010 SQ31, and 2010 TL69. Astrometry, the following elliptical
orbital elements by G. V. Williams, and an ephemeris appear on MPEC 2010-X102.
