Abstract

The writer made 60 photometric measurements of Saturn + rings between Nov. 5, 2004 and Jan. 21, 2005. The normalized magnitudes of Saturn for a ring tilt angle of 22° are B(1,0) = -8.55 ± 0.01, V(1,0) = -9.60 ± 0.01, B(1,0) = -10.27 ± 0.01, and I(1,0) = -10. 4 7 ± 0.01; the corresponding solar phase angle coefficients are cB = 0.027 ± 0.006, cV = 0.021 ± 0.005, cB = 0.020 ± 0.005, and cB = 0.022 ± 0.005. The 2005 opposition surge values (in magnitudes at a = 0°) are B = 0.24 ± 0.05, V = 0.18 ± 0.05, R = 0.16 ± 0.05, and I = 0.27 ± 0.05.
