LUNAR OCCULTATION OF JUPITER'S GALILEAN SATELLITES
     D. W. Dunham communicates the following prediction of the
reappearance of Jupiter's Galilean satellites at the moon's dark limb
(27-percent sunlit) on July 21.  The local circumstances below are
for Wellington (dT_W) and Lake Tekapo (dT_L), New Zealand (cf. IAUC
