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[degrees] are: B(1,0) = -8.55 [+ or -] 0.01, V(1,0) = -9.60 [+ or -] 0.01, B(1,0) = -10.27 [+ or -] 0.01 and I (1,0) = -10.47 [+ or -] 0.01; the corresponding solar phase angle coefficients are: [c.sub.B] = 0.027 [+ or -] 0.006, [c.sub.V] = 0.021 [+ or -] 0.005, [c.sub.B] = 0.020 [+ or -] 0.005 and [c.sub.B] = 0.022 [+ or -] 0.005. The 2005 opposition surge values (in magnitudes at [alpha] = 0[degrees]) are: B = 0.24 [+ or -] 0.05, V = 0.18 [+ or -] 0.05, R = 0.16 [+ or -] 0.05 and I = 0.27 ...
