OUTER SATELLITES OF THE GIANT PLANETS
     During the past year and a half the number of known outer satellites (or
candidate outer satellites) of the giant planets has more than doubled.
Although the Central Bureau is charged with providing provisional designations
for new satellite candidates, to provide all the astrometric, orbital and
ephemeris information requires a prohibitive amount of space on these
Circulars.  Readers should be aware that, by arrangement with IAU
Commission 20, full astrometric and orbital information is now being included
in the Minor Planet Circulars, and full details on S/2000 S 5- S 10 will
appear in the Dec. 11 batch.  In the future, the Minor Planet Electronic
Circulars will be used to provide the initial information more completely.
     Further observations are particularly required of S/2000 S 3, while
recent observations of S/2000 S 4 indicate a significant ephemeris revision:
