Solar remnants of AR3664 - Set 2 of 3

Acquisition type: Lucky imaging

Time lapse of Solar activity from the region of AR3664 as it passes the Suns limb showing the areas large magnetic fields at work. If we look carfully, part of Sunspot AR3664 is still visible at the edge. AR3664 was the sunspot that produced the beautiful Northern Lights on May 10-11, 2024. The time lapse consists of 18 images combined, spanning 36 minutes, starting at 19:41UT to 20:17UT. The height of the largest loop spans to about 40,000 miles above the surface. For a more detailed explanation about the physics of the activity, my dear friend Andrew Rosado, who is pursuing his PhD in Solar Astro-Physics, has given me a much better understanding of what is happening. I hope you find his description interesting and educational. I know I always do!

From Andrew:

These solar filaments follow a near-perfect magnetic loop emanating from the chromosphere. The loops formed as large magnetic regions of the surface, divided into different polarities, interact. At intersections of these different polarity regions, Polarity Inversion Lines form. When following PILs’; magnetic breakout can occur due to violent magnetic interactions, forming a filament above. This facilitates the substantial quantity of comparatively cooler and dense plasma, supported by the resultant magnetic fields against solar gravity. This makes the structure you see in this data, a near perfect example of the magnetic interaction at work at the Sun’s surface.

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.
