Panic Sunspot
Starting little by little in solar with white light, while still learning, I caught a spot with an interesting shape that reminded me a lot of the movie "Panic".
One of the most interesting phenomena that happen on the surface of the Sun, and which is very easy to observe, are sunspots. Although they had been seen since remote antiquity by Chinese astronomers, the first European to observe and describe them systematically was Galileo Galilei, in 1613.
Sunspots is an appropriate term. They look like spots on the Sun's disk. A sunspot will have a very dark central region called the umbra. It is often surrounded by a less dark halo known as the penumbra. The umbra is dark because it is cooler (at about 3,500°C/6,300°F) than the surrounding region (at about 5,500°C/10,000°F).
Spots change within a period of several days. Photographing the detailed appearance and location of sunspots over several days can provide a clear illustration of this fact.
They also travel across the Sun as the Sun rotates around its axis. Because the Sun is fluid, it doesn't rotate like a rigid body. A spot near the equator will need about 25 days to complete one rotation. A spot near the pole, if any, will need a month to complete the journey. Follow-ups over a period of several years will also reveal the 11-year sunspot cycle. During this period the number of spots goes from maximum to minimum, and back to maximum.
The photography and tracking of sunspots, is one of the most interesting subdivisions of astrophotography and does not require very expensive equipment to be done in white light.

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.
