This is the second time that Juels and Holvorcem have won the award. In 2003 the pair was recognized for discovering C/2002 Y1. That same year Broughton was chosen as one of the recipients of the Planetary Society's Eugene Shoemaker Near-Earth Object (NEO) Grants. He used to the grant money to purchase a CCD camera for NEO hunting and tracking from the Southern Hemisphere.
Established in 1998 in memory of American businessman Edgar Wilson, the award is given to amateur astronomers (or professional astronomers acting in an amateur capacity) who, during the 12 months preceding June 10th each year, find one or more new comets using privately owned equipment.
