An apparently asteroidal object was discovered by the LINEAR project on 2003 November 18 (observed on only two nights) and given the designation 2003 WC_7. The object was discovered independently on January 31 by the Catalina Sky Survey and then posted on the NEO Confirmation Page. As a result, it has been found to show cometary appearance on CCD exposures taken by J. Young (Table Mountain, 0.6-m reflector, Feb. 1) and by G. J. Garradd and R. H. McNaught (Siding Spring, 1.0-m f/8 reflector, Feb. 1). PanSTARRS discovered what was thought to be an unknown 20th magnitude comet on 2015 October 10, though the discovery report did suggest that it might be a recovery of 2003 WC7 (P/LINEAR-Catalina). Further astrometry confirmed the identification.
