Title: Jupiter Loses Big Belt; Great Spot Left Hanging

Jupiter has lost a belt, giving sky-watchers an unusual view of the gas giant planet's pale bottom.

Two wide stripes—known as the equatorial belts—normally circle the huge planet, products of the fast-moving jet streams that roar through Jupiter's atmosphere.

The belt seems to disappear every 12 years or so which coincidentally fits in with Jupiter's orbital period around the Sun.  I wonder if there may be some sort of link?   :dunno:

could be some kind of heating effect, but I doubt it - its probably more an odd coincidence. Its worth keeping not of though. I wonder how old observations we could dig out and try and fit a trend... there is a paper in this...

well just collating the old results and making some conclusions would indeed probably be a good masters project.... hmm....

LOL, how many more Masters do you need?   :laugh:  One for Lizzie maybe?  Surely she must be on her way to a PhD now?
