P468 Prediction
(as of: 2006 10 04)
The following prediction results from the analysis of 19 strip scans obtained at the Lowell Observatory Astrograph by MIT observers during 2005 and 2006, compared with an offset to the light-time corrected, geocentric JPL Horizon's ephemeris (System DE413 - Pluto source file; PLU013; Earth center source file; DE405) determined by comparing the Pluto system barycenter to the measured barycenter from the strips. The offsets between the measured RA and Dec of P468, 2UCAC 25819301, and its UCAC2 values are also given in the table.
