PROBABLE NEW SATELLITE OF SATURN
     Dr. Audouin Dollfus, Meudon Observatory, reports the discovery
of a probable new satellite of Saturn.  The satellite, of magnitude
14, is very close to the edge of the ring and moves in an orbit of
estimated diameter 315 000 km.  The provisional revolution period
is 18 hours.  The object was observed on three plate: at eastern
elongation on December 15 and at western elongatin on December 16
and 17.  Dr. Dollfus states that further observations are needed.


COMET RUDNICKI (1966e)
     Dr. Axel V. Nielsen, Ole Romer Observatory, points out that
at its descending node Comet Rudnicki passes very near the orbit of
the earth.  Its heliocentric distance would then be 1.02 AU.  He
suggests the possibility of observing meteors associated with the
comet on about 1967 June 7.

     Further precise positions have been reported as follows:
