Ground-based charge-coupled device images of Saturn were obtained at the Cassegrain focus of the 1.52-m telescope at the Calar Alto Observatory (Andaluc¿a, Spain) during the 1991 opposition. The images were obtained in and out of the absorption methane bands at 6190, 7250, and 8900 ¿ under very good seeing conditions. A Bayesian deconvolution technique was employed in the restoration procedure. The derived absolute reflectivities and band depths at some locations of the disk are provided in tables appropriate for analysis in terms of scattering models. Possible temporal variations between the reflectivities found here and those reported by West et al. (1982) are discussed. No longitudinal variations in reflectivity larger than a 4% level were found. Some images showed bright spot activity at the equatorial region. ¿ American Geophysical Union 1993
