I've heard that this is apparently at least a quasi-periodic phenomenon, but can't locate any reputable references to support that.

Regardless, yet more evidence that Jupiter is a very dynamic world.

Readers of The Planetary Society Blog were not left out. Emily says, "...apparently, this is an event that happens rather more frequently than the Saturnian equinox, once every 3 to 15 years."

Next we are going to hear that Jupiter's pants fell down. No pictures please.

It isn't shrinking...okay Jupiter lost a few pounds and its old belt no longer fit. My understanding is that Europa is knitting Jupiter a new one. It should be done in a few months.

For a nice series of before, during, and after shots, check out the Jupiter images from the first couple of months of this year: http://alpo-j.asahikawa-med.ac.jp/Latest/J...9Apparition.htm

It looks a bit like the Pioneer 10 images of Jupiter. Although in the Pioneer images, the red spot is HUGE.

A quick comparison with the Pioneer 10 view of Jupiter:

my understanding is that the higher light colored clouds are just covering it up , and this happens every now and then .

The very deep solar minimum we are experiencing may be a correlation to the missing band.
It may be interesting to compare the last 50 years of Jupiter banding to solar input (at Jupiter's distance) as well as the solar magnetic field out there (i.e. cosmic ray bombardment as a function of magnetic fields). Another lead may be the inputs of past Coronal Mass Ejections out to Jupiter's neighborhood). The current solar cycle is projected to last a slow-pokey 13+ years compared to the nominal 11 years. A new Dalton-like Minimum may be in the works...could Jupiter's atmosphere respond that quickly?

Cheers

Ian R I like the comparison you did. I was thinking the same thing when I first saw the images.
The great red spot looks different.
