Description

Sunspots (20230925) - distinctive diagonal

A large, striking diagonal runs across the sun's disk, attracting attention through four very different groups of spots in the visual spectrum. The chaotic group of spots in the active region AR13445 below the center of the solar disk, which looks like an open star cluster, is particularly striking.

A look at the associated SDO HMI magnetogram   shows a huge magnetic field, its plus and minus poles (white on the left, black on the right) very pronounced and close together each other, as well as a very large and dominant negatively polarized zone below.

In layman's terms, it looks to me like the extensive black (negative) magnetic zone is fighting for dominance with the white (positive) magnetic zone, like two teams on a sports field. And because neither party has been able to prevail on this sports field (AR13445), we only see countless small "crumbs" and no solid, large spots - quite a mess!
