software for integrating a geocentric orbit?

	An asteroid-hunting team here in Houston spends half of their
weekends hunting for new asteroids. On November 3 they thought they had
a rather fast-moving one, and excitedly followed it making observations.
The minor planet center bounced it as an object in high earth orbit and so
not in their bailiwick. :-)

	They already have software that will fit asteroid orbits given a
set of observations. Is there software available that will fit a geocentric
orbit (maybe taking into account perturbations by the moon, sun, etc) given
a set of observations? That way they could see if anything suspicious fit
a geocentric orbit too well, and if it fit, not bother the minor planet
center with the news.

	(If anyone is interested in trying to identify their "Earth-crossing
asteroid" I can send the observations. It would be very interesting to know
what they saw.)
