A revised orbit was published this morning, which should be reliable within a few arcminutes at the time of closest approach. http://cfa-www.harvard.edu/mpec/K04/K04F26.html Note that you wanna stick the second set of elements into software. This one has epoch for yesterday, which because of the very substantial perturbations, is necessary to find it "now". As you can see, the orbit for the standard epoch several months from now is very greatly changed in period, semimajor axis, inclination, etc. Minimum distance is now only 30,000 miles (50,000 km). You should be able to get ephemerides for your location (geocentric won't be good enough) using either the MPC site: http://cfa-www.harvard.edu/iau/MPEph/MPEph.html ...or the JPL Horizons site: http://horizons.jpl.nasa.gov ...or the Univ of Pisa 'NEODys' page for this object: http://newton.dm.unipi.it/cgi-bin/neodys/neoibo?objects:2004FH;main \Brian -- See message header for info on list archives or unsubscribing, and please send personal replies to the author, not the list.
