From 54 observations 2000 Feb. 5.
The above orbit is identical with that of comet C/2000 C3 (MPEC
2000-C51), except for the difference of 0.60 day in T. Although slight
systematic effects remain in the residuals (effects that to some extent
remain if independent parabolic orbit solutions are made) the two comets are
clearly related.
