Infrared Data from Saturn's Polar Hot Spot

The view shows temperature data from the Cassini spacecraft Composite Infrared Spectrometer (CIRS) overlaid onto an image from the Imaging Science Subsystem (ISS) wide-angle camera. The CIRS data refer to a depth in Saturn’s upper stratosphere where the pressure is 0.5 millibars (324 kilometers above the 1-bar level). The CIRS data show a very small hot spot over the pole, similar in size to the “eye” of the storm seen in ISS images.
