Scientific paper

A photon-counting speckle interferometric study of Pluto and its moon, Charon, has used 12,000 speckle interferograms to yield position angles. In order to solve such measurements' inherent 180-deg ambiguity, a long exposure photograph of the speckle data on the second night of observation was calculated. Due to the motion of Charon, the position angle changed from 188 to 170 deg, while the separation changed from 0.63 to 0.95 arcsec.
