Acquisition type: Lucky imaging

This surface animation shows a lot of activity with some very bright areas. The duration of the animation is only about 30 minutes.
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
We will be looking at and understanding a bit of what is happening in the animation. The first point of note is the detailed contrast in the spicules within the chromosphere. These spicules are the almost hair-like structures observed while viewing the animation, these spicules rise directly out of the chromosphere over the course of 10-20 minutes. Spicules are massive energetic jets of plasma traveling upward from the photosphere beneath the chromosphere at 20-120 km/s. The result is extremely visible surface dynamics, as in this timelapse the chromosphere can be seen to transform near constantly over the course of an hour. Of further interest is the dark filament traveling across the center. It could be assumed that it is merely a hole, however it is actually a magnetic loop that has formed above the Polarity Inversion Line and parallel to it. It’s extremely fascinating because the dark region is cooling plasma being channeled across the magnetic loop. This cooling plasma presents as an optically dense and, therefore, dark spot when held against the surrounding temperature and optical densities.

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.
