POSSIBLE MAGNITUDE VARIATIONS OF SATURN'S SATELLITES
by K.E. Chilton, Planetary Coordinator
For many years it has been known that he magnitude of Iapetus, Saturn's outermost moon, is variable. Recent observations have indicated that some of the other moons may vary in brightness, too. (Refs. 1,2) This was pointed out in Planetary Bulletin No.9. However, observers were left ot their own devices to work out the positions of the satellites.
