Sunspots (20230719) - magnetic influences

It is amazing that the visible spots of the apparently long and narrow active region AR13373 - visible prominently in the center of the solar disk - are so close to the Sun's equator.

Is this the reason for their chaotic appearance? In any case, a look at the SDO HMI magnetogram shows that there is a lot "more to it" than the spots suggest: A strongly pronounced magnetic positive pole (right, white) stands seamlessly opposite an equally strong magnetic negative pole (left, black), side by side and close to the equator. The magnetogram of AR13372, which is to the right above AR13373 and consists of a chaotic group of spots to the left and a large sunspot that appears very calmt to the right, looks very similar to the former: A large, strong positive pole to the right and a similarly sized negative pole to the left.

I would be very interested in whether and to what extent the magnetic processes in the active regions have an impact on the number and shape of the sunspots that arise from them.

Expert comments very welcome!

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.
