ABSTRACT
A total of 52 photoelectric magnitude measurements of Saturn were made between Sept. 27, 1998 and Jan. 5, 1999. The V-filter measurements match up well with values predicted in the Astronomical Almanac. The selected normalized magnitudes for Saturn are: B(1,0) = -8.45[+ or -]0.02, V(1,0) = -9.44[+ or -]0.01, R(1,0) = -10.10[+ or -]0.02 and 1(1,0) = -10.35[+ or -]0.02 while the selected solar phase angle coefficients for the B, V, R and I filters are: 0.047[+ or -]0.008 0.035[+ or -]0.002, 0.038[+ or -]0.009 and 0.040[+ or -]0.009 respectively. Results over the last three years show that the solar phase angle coefficient in the V-filter changes with the ...
