Lunar Occultation of Jupiter's Galilean Satellites

D. W. Dunham, Cincinnati Observatory, communicates the following prediction, computed by F. Fekel, University of Texas, using data supplied by K. Aksnes and himself, of the reappearance of Jupiter's Galilean satellites at the dark limb of the moon (3-percent sunlit) on May 27. The columns headed dT_Z, dT_H and dT_R give the differences between the times of emersion of the indicated satellite and the center of Jupiter as observed at Zurich, Herstmonceux and Rome; d gives the duration of emersion; the column dP gives the difference in position angle at reappearance and dR.A. and dDecl. the differences in apparent right ascension and declination.
