Jupiter with GRS in transit and two moons, Sat 1 Jun 2019 AEST.

Very brief window of fair seeing saved this session from being a complete write off. Publishing to document continuing disassembly of the Great Red Spot.. more ejected material is seen here on the south eastern edge. The storm has drastically shrank in size over the last two weeks and now sports a thin dark streamer within northern part of its halo.

Meanwhile Io is making a transit immediately north of the NEB outbreak with its shadow ahead in the east. Largest moon Ganymede has nearly completed re-emergence from behind the planet.. despite ordinary seeing albedo detail is detectable on the Jovian facing hemisphere.

I've derotated eight best stacks covering recording period between 10:52 and 11:03 pm Canberra time, giving a total of 5760 frames for this picture. To correct WinJUPOS smearing of Ganymede I've composited a single 80s stack view with a mid-point of 10:58:30 pm (ie. 42 seconds later). Moons are always so challenging to process..

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.
