Precovery images of the comet were found by Maik Meyer in December 2004.[6] There were two images from 1997, two images from 1991, and three images from 1990.[7]

During the 2005 perihelion passage the comet brightened to an apparent magnitude of about 16.[8]

Around November 17, 2114, the comet will pass about 0.117 AU (17,500,000 km; 10,900,000 mi) from Jupiter.[9]
