Tom Gehrels reported his discovery of a faint (20th magnitude) comet on 2 October
2000 in images taken with the Spacewatch telescope at Kitt Peak, noting it to have a
4" tail in p.a. 170 deg. T. B. Spahr, Minor Planet Center, linked it to an asteroidal
object observed on 23 and 26 September reported earlier by LINEAR and then found
LINEAR observations made on 1 September. At the request of Gehrels, P. Massey
obtained images of the object in subarcsecond seeing with the 4-m Mayall Telescope
at Kitt Peak on 3 October, showing the comet to have a fan-shaped structure 4" long
spanning p.a. 0-80 deg.
