Processing some old data.

Animation showing a large prominence and some of the solar activity from 6-17-23. Animation consisting of 17 frames, starting at 14:25 UT, ending at 14:57 UT. As always, I should have gone longer but had an interruption in my data accumulation. The span of this prominence is about 120,000 miles with a height of approximately 10,000 miles . Part two of this animation is to follow.

For a more detailed explanation about the physics of the activity, I would like to hand that over to my dear friend Andrew Rosado, who is pursuing his PhD in Astro-Physics. He knows way more about the dynamics of what is going on and I hope you find his description interesting and educational. I know I will!

From Andrew:

This is a relatively interesting prominence, it's the most recent animation to present a prominence this low in the chromosphere. To cover a prominence are jets of plasma that are thermally insulated by the magnetic field containing them. As a result, the thermal gradient results in differing optical densities and therefore structure. Despite its relatively low altitude, the prominence is likely relatively cooler than a prominence that reaches out far into the corona. This is a product of the increasing temperature that exists with an increase in distance from the core. At the transition zone, which is about 8500km outwards from the convection zone. Temperatures in excess of 1,000,000 Kelvin.

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.
