Great set of images.
Might be interesting to see if Trevor ( Quark ) in Broken Hill has imaged the possible storm as he is a Saturn aficionado.
Tried to get some avis' earlier tonight of a double shadow transit on Jupiter but the seeing was garbage so I'm not optimistic of getting any worthwhile images from the vids. Pity, as this was about the last chance for this season of capturing a double transit, plus Red Spot.
