This section provides, courtesy of the Minor Planet Center's Ephemeris Service, all unusual objects extrapolated from our lists MBPL (Minor Body Priority List) (objects with a diameter>240mt) , SAEL (Small Asteroids Encounters List) (objects with a diameter<240mt) and PCEL (Planetary Close Encounter List).
More objects could be selected simultaneously and ephemerides obtained just pressing the enter (return) key or clicking on the "Get ephemerides" box.
By default, supplied ephemerides are geocentric. Topocentric ephemerides may be selected by entering a three-character observatory code.
The returned ephemeris positions are given hourly in Universal Time for the next 25 hours but suppressed if the object is below, or the sun is above, your local horizon.
Astrometric observations of any of the following objects should be sent directly to the Minor Planet Center Minor Planet Center. at: obs@cfa.harvard.edu.

                  Oi ->Useful for orbit improvement (based on orbit uncertainty).
                  Dv ->Desirable as not numbered VI.        Rt ->Desirable as radar target.
