                            PLANETARY SECTION


Greetings!

This is the last bulletin that you will receive under this heading. This does
NOT mean that Planetary Bulletins will not be issued any longer, but merely
that the various Sections have been abolished and the Job of co-ordinating
observations has been given to C000CA.

                     PLANETARY SECTION


POSSIBLE MAGNITUDE VARIATIONS OF SATURN'S SATELLITES:


For many years it has been known that the magnitude of Iapetus, Saturn's
eighth moon, is variable. Recent observations have indicated that some
of the other moons may vary in brightness too (ref. 1, 2). This was pointed
out in Planetary Bulletin No.9. However, observers were left to their own

GREETINGS fellow planetary observers! Since the last bulletin was issued, winter set
in and I was expecting a corresponding drop in the number of observations received.
However, this is not the case! Evidently many of you are using anti-freeze for blood,
as we have been getting a good number of mid-winter observations.

                              PLANETARY SECTION

Summer has passed and now the Centres should be starting their programs again. We
hope these will include observing the planets.

MARS:   Drawings of this planet made during the recent apparition would be appreciated
as arrangements have been made to exchange observations with the Mars section of the
British Astronomical Association.
