SATURN IN LATE 1993

摘要

A combination of photometric and visual/photographic studies of the planet Saturn were conducted during September and October of 1993. Solar phase coefficients in mag./deg., of Saturn (globe+rings) measured through Johnson B, V, R and I filters were 0.055±0.007;0.054±0.005;0.047±0.010 and 0.053±0.007 respectively. The normalized magnitude of Saturn (excluding the rings) was V(1,0) = -8.84±0.04. Visual observations and photographs indicate that Saturn has returned to an appearance similar to that which was observed in 1989 prior to the occurrence of the large white storm of 1990.
