Improved luminosity model and albedo for Saturn

Abstract

The globe of Saturn is brighter than previously reported as indicated by its absolute opposition magnitudes in the UBVRI band passes which are -7.080, -7.842, -8.914, -9.587 and -9.606, respectively. The geometric albedo in V is 0.501 and it peaks in the R filter at 0.567. The brightest apparent magnitude of the system in the V-band is -0.61 and the faintest is +1.31. The B-V color index can be as blue as +0.93 and as red at +1.12.
