NEAR-INFRARED CVF SPECTROPHOTOMETRY OF SATURN IN 1992

Absolutely calibrated measurements of the reflectivity of Saturn in 19 92 are presented. The observations were carried out using a Circular V ariable Filter in combination with a photometer with a single element InSb detector at the 1.54 m Carlos Sanchez infrared telescope of the O bservatorio del Teide in the Canary Islands (Spain). The spectral rang es covered were 1.4-2.4 mu m and 2.6-4.5 mu m. Besides the measurement s at the disk, values of the reflectance of the Saturn's rings in the West Ansa were obtained. A comparison with the few related published w orks is made, and the significant spectral features in this wavelength region are discussed. A spectrum of Jupiter obtained in 1993 is also presented and compared with spectra obtained by us in 1991 using the s ame instrumental configuration.
