The Lowell Observatory Near-Earth Object Search (LONEOS) survey program
discovered this apparently asteroidal object on 25 November 2000, at magnitude
17.2. It was designated 2000 WT2000. Several prediscovery images were found by
the Lincoln Near Earth Asteroid Research (LINEAR) program going back to 27
September 2000, the earliest of which were magnitude 18.9.
C. W. Hergenrother (Catalina) obtained CCD exposures with the 1.5-m reflector on 13
February 2001, which revealed a highly condensed coma 9.7 arc seconds across,
with a red magnitude of 16.3. There was also a tail extending 8.0 arc seconds toward
PA 110°. The cometary activity was subsequently confirmed by several observers.
