Saw your article about the large sunspots facing Earth and took out my 70 - 300 lens with the sun filter I used for the last eclipse. I captured several photos with this odd, shaped triangle around the large sun spot. I wish I had a sun filter for my 400 mm L series glass!!!

Canon EOS 5D MK IV 70 - 300 mm 1:4 - 5:6 with a Firecrest IRND Sun filter 1/500 Sec., f/16, ISO200.

Photoshop temperature shift to orange, and picture crop.
