The solar system is a happening place this week! I just learned of a major storm in Saturn's northern hemisphere, being monitored by the usual band of talented amateurs. See this site for a list of recent images. Chris Go's site has a particularly nice image.

Straightforward combo of HiPassMT2 RGB[MT3,MT2,CB2]. Some channel mixing between the methane transmission layers and a gentle contrast enhancement:
Blue is deep atmosphere (much methane absorbtion), white is upper levels (light reflected before methane can get absorbed) .

Attached Image


Amazing detail in this! The bright upwelling at the upper left of the image seems to have a dark spot in MT2 and MT3 images (eyewall??). Immediately to the SW of the upwelling is a deep blue vortex of descending air. Cloud patterns around this spot show a counterclockwise pattern.

And a shockwave can be seen trailing from the W edge of the storm down through the southern belt almost to northern edge of the the Equatorial belt.
