ABSTRACT
The writer carried out brightness measurements of Saturn and its rings with four different color filters. The selected normalized magnitudes of Saturn + rings for a ring tilt angle of 14[degrees] are B(1,0) = -8.25[+ or -]0.03, V(1,0) = -9.36[+ or -]0.03, R(1,0) = -10.01[+ or -]0.04 and 1(1,0) = -10.16[+ or -]0.04. The opposition surge values for Saturn + rings on Feb. 11, 2007 (solar phase angle = 0.15[degrees]) were 0.19 and 0.06 magnitudes for the B and V filters respectively. The writer concludes that the B-V and V-R color indexes of Saturn + rings do not change much when the solar phase angle drops from 6[degrees] to 1[degrees]. The rings become a ...
