The sun is feisty lately.
This solar cycle has been quite a bit more active than forecast.

It’s about the same size as our Milky Way, but is classified as a “flocculent spiral” galaxy due to its poorly defined spiral arms. The more distant edge-on spiral galaxy on the right doesn’t show…
The Whirlpool Galaxy
