Jupiter - the Oval BA approaches the GRS

Recently I posted some close up images of the magnificent Jupiter, but showing longitudes that didn't include the Great Red Spot (GRS). More recently on the 13th August 2020 I had a narrow window of a single cloud free night, with the GRS well placed. Not only that the seeing was excellent. This image is basically north up, although once again I tilted the planet for aesthetic reasons.The NEB is remarkably chopped up. The NNTeB has quite a long reddish brown barge on the p side of the CM near the limb.

The image has really good resolution of the GRS, which can be seen to have a quite dark but small central part. There is an annular section with a more orange colour and outside that a darker ring that curls around to two small lighter coloured ovals on the f side. Outside this there is an amount of red material which I presume is a remnant of the latest flake activity. There are also two dark areas just on the p side of the GRS in the RSH.

The Oval BA shows distortion as it approaches the GRS and it exhibits some interesting dark structure as an internal ring, although the periphery is very white.

The complex wake of the GRS has large regular shaped and decaying eddies.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
