Hi,
There are a few exciting things that I can think of...
Daniel K. Inouye Solar Telescope (DKIST) is the newest solar telescope built in Hawaii and just recently took an amazingly detailed image of a sunspot. This is mostly to show that the telescope works, but the image is just amazing in its detail. You can read about it here:

It isn't yet clear what causes these and how/if they might relate to heating the solar corona. You can read about it here:

The Sun has been really quiet lately, but last November there was the first large solar energetic particle event. This was observed really well by Parker, but also seen by spacecraft all around the Sun, including STEREO-A, Solar Orbiter, and missions like ACE, Wind, and SOHO near the Earth. This means the particles were spread all the way around the Sun pretty quickly. We're still trying to figure out how that happens.
