C/2000 OF8 Spacewatch
more info
Comet C/2000 OF8 was discovered on 24 July 2000 with Spacewatch Research project (Steward Observatory, Kitt Peak), that is a year before its perihelion passage. It was observed until 1 August 2001.
Preffered solution given here is based on pre-perihelion data spanning over 1.02 yr in a range of heliocentric distances from 4.56 au to 2.17 au.
Comet had its closest approach to the Earth on 4 June 2001 (1.390 au), about 2 months before perihelion passage.
This is Oort spike comet.
