Occultation of C313.2

RCS star position is taken as an average of 11 measurements of the star position by Ron Stone using the FASTT from Jun 18 to Jul 6 2004 (Epoch 2004.5). Charon's position is taken from the unmodified, light-time corrected, geocentric JPL Horizon's ephemeris (PLU006, DE-0406, LE-0406).
