Here is my first opportunity to image the new storm in Saturns southern hemisphere, in average-to-good seeing this morning for a short while. It shows up clearly in this image, in fact it looks like two storms that are close together, separated only slightly in longitude :-)
I've been a bit more aggressive with the enhancement in this image so that the storm(s) are clearly shown as well as various cloud detail around the equatorial region. Rhea is visible above the rings to the right hand side.
The sudden brightening over this last week was supported by the detection of a much higher rate of SED's.
This increase in activity has also been accompanied by a elongation in longitude which, for sure, could be explained by 2 storm cells.
As you say, certainly looks like it has split into 2 storms, back in 2008 the major storm of that year also broke up into multiple smaller storms but they were spread out over a larger region.
