Continuing or Perpetual Storm? (MULTISPECTRUM; credits: Lunexit)

Caption NASA:"The longest-lived continuously monitored electrical storm ever observed on Saturn continues to churn through the tempest-tossed region nicknamed "Storm Alley" because of its preponderance of storm activity. This image of the storm was taken about 5 months after it was first detected by Cassini's Imaging Cameras and the Radio and Plasma Wave Science Experiment.

This view looks toward the unilluminated side of the Rings from about 1° above the Ring-Plane. The bands of the Ring shadows blanket the Planet at the top of the scene.
The image was taken with the Cassini spacecraft wide-angle camera on April 23, 2008 using a combination of spectral filters sensitive to wavelengths of polarized infrared light centered at 752 nanometers. The view was acquired at a distance of approx. 1,2 MKM (such as about 760.000 miles) from Saturn.
Image scale is roughly 70 Km (about 43 miles) per pixel".
