This extreme close-up details the magnificent sunspot that was on the surface of the Sun late-Nov to early-Dec 2020.

This thing is huge.

Check the second revision to see it compared with the scale of the Earth. That’s a lot of bananas!

In fact, this is the largest sunspot I have ever had the chance to image. This may be my only shot at it, too, since the clouds have been relentless. I took a video of 5000 frames, graded them carefully, stacked them, and really focused my editing on bringing out the smallest of details.

Since I like to include little science facts...

Did you know that sunspots are not given a number designation? Only active regions get an archived number, and these may or may not include spots. These consecutive numbers are issued by NOAA and that process began in January 5, 1972. By 2002, those numbers had reached 10,000. From that point on, it became typical to just drop the “1” and keep it as a four digit number. So this sunspot actually resides in Active Region 12786, but is more commonly referred to as AR2786. Now you know.

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.
