Abstract: 

With using of a spectrophotometric measurements data of 2015, relations of values of imaginary part ni of the refractive index of aerosol was determined for latitudinal belts 17°N, 33°N, 49°N and 66°N of Saturn’s disc. We determined a steady in time tendency to decrease the relative values of ni when moving northward from the equatorial region of the disk to the latitude 49°N, inclusive. A significant difference between the values of ni in the 17°N and 49°N from other studied latitudinal sections of the disk of a giant planet is determined. The relative magnitude of the ni at the latitude 66°N in 2015 is close to its value at 40°N in 1980.
