Jupiter with the Oval BA and the GRS on the limb. (Niall MacNeill)

Jupiter with the Oval BA and the GRS on the limb.

Acquisition type: Lucky imaging

After a first run on Jupiter, then Mars, I thought the seeing was getting much better so I went back to Jupiter in the hopes of a run with the recent Perijove path of the Juno space probe fairly central. And it was really extraordinary seeing for 4 RGB runs before it went off again. As a result the resolution of the Juno Perijove path is very good and significantly better than my previous efforts where the seeing wasn’t as good.

In the STB to the north and on the p side of the Oval BA, there is a subtle series of what look like light purple waves against the white of the STB just south of the SEB. Immediately on the p side of A8 there is an interesting feature which has a north-south component and then on its p side a series of radiating arms. The structure inside the Oval BA is quite well resolved and shows a dark centre and brighter ring inside the dark annulus. It has a touch of red colour at the extremities to my eyes. In the NEB there is an extremely bright break out and the festoon to its south is enormously dark. In fact I was looking through the eyepiece in another scope and it was so prominent, I went back to the feed on the computer screen to see in more detail what it was.

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.
