Whilst monitoring members of the Themis familly of asteroids for signs of cometary
activity, H H Hsieh and Dave Jewitt of the University of Hawaii imaged asteroid
118401. Images taken on 26 November 2005 with the Gemini North telescope
showed a tail 7" long, and confirming images were taken in December. The asteroid
was found by LINEAR. In June 2006 the Committee on Small Bodies Nomenclature
agreed to name and number the comet, although the asteroidal designation will be
used for archiving any astrometry.
