I got a short bulletin for this evening. I didn't find too much on JPL. I thought this was kind of interesting. It starts off from faceweather.com, dated today. A potentially dangerous sunspot.

Movies of the active region show it's looking quite risky. And here's an explanation of X-class solar flares.
