Abstract
Predictions are presented for
54 occultations by Uranus' ring system,
24 occultations by Uranus,
22 occultations by Neptune, and
10 possible occultations by Pluto
during the period 1985 through 1990.
Notable occultations by Uranus occur 24 May 1985, 16 April
1987, 27 May 1990, 21 June 1990, and 7 August 1990. The best Neptune
occultations are on 7 June 1985 and 25 May 1990. Of the Pluto
events, there are six which are nominally observable somewhere on
the earth, although uncertainties in Pluto's position combined
with uncertainties in the star positions preclude prediction of a
ground track until just before the events.
