SATURN X (JANUS)
     A cable from Dr. A. Dollfus, Meudon Observatory, states that
the new satellite of Saturn was recorded on four plates taken by
J. Texereau at McDonald Observatory on 1996 October 29 about 03h UT
and also on one plate taken by the Pic du Midi staff on 1967 January
9 at 19h03m UT.  The 13 available plates yield an almost circular
orbit in the equatorial plane with a = 2.65 equatorial radii and
P = 17.975h.  The satellite was at greatest eastern elongation on the
discovery date 1966 December 15 at 18h20m UT.
     Dr. Dollfus proposes the name Janus for the new satellite.


DEFINITIVE ORBITS OF COMETS
     Dr. G. Sitarski informs us that he intends to determine definitive
orbits for Comets Kilston (1966b), Barbon (1966c), Ikeya-Everhart
(1966d) and Rudnicki (1966e).  He requests that observers
send positions to him at the following address: Astronomical
Institute of the Polish Academy of Sciences, Warsaw, A1,
Ujazdowskie 4, Poland.


PERIODIC COMET TUTTLE (1967a)
     The following precise positions have been reported:

Tomita (Tokyo Astronomical Observatory).  Precise measurements of
   the recovery observations (IAUC 1991).
Milet (Nice Observatory).  Weakly diffuse, intense nucleus.
