Spatially resolved infrared observations of Saturn. III - 10- and 20-micron disk scans at B prime = -11.8 deg
Disk scans of Saturn at 10 and 20 microns were obtained when the Saturnicentric solar declination B prime was -11.8 deg. The scans show little change from scans obtained when B prime was -16.3 deg. This could result from the long radiative time constant of the Saturnian atmosphere. The observations...
