P384.2 UCAC 2.0 Prediction
(as of: 2006 6 1)
The following prediction is the result obtained from the analysis of 60 strip scans obtained at the Lowell Observatory Astrograph by MIT observers in the summer of 2005 and Amanda Bosh (Lowell/BU) in the spring of 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 P384.2 and its UCAC2 values are also given in the table.
