Large Sunspot Group Visible

The sun remains active in 2025 and is a good target for observers. On August 28, Spaceweather.com reports, "A phalanx of large sunspots is facing Earth. They're so large, photographers are catching them in the sunrise and sunset."

The sun can be observed through while light-filtered telescopes, hydrogen-alpha telescopes, and a Sun Funnel. Do not look directly at the sun without proper protection. On August 28, 2025, I had clear skies and an open horizon near sunset. With a Sun Funnel I was able to capture Sunspot #4197 and others.

Big solar action can sometimes yield other effects, like aurora, so be on the lookout.
