G'day all,

 

I took another stab at chasing the mythical red oval in the southern polar region. Catching it tonight required imaging well before nightfall (sunset was at 08:35 UTC). Fortunately, Jupiter was at 31˚ elevation when I caught it. To my surprise, Ganymede emerged from a mole on Jupiter's limb while I imaged:

The southern polar region didn't derotate well, so I had to kludge it a bit—the result is offset slightly from the rest of the image (but at least it's sharp):

The color is subtle, but the hue difference comes across if I drive up the saturation:

I'm curious if all these ovals have designators…
