How about some nuclear fireworks for July 4th? Interestingly we have a smooth, featureless sun (with my optical equipment at least) seen a few minutes ago on July 4th, 2017. No sunspots, at all which surprised me. Apparently, our star the sun is in a period of the longest stretch with no sunspots since April 2010, indicating that the solar activity may be approaching a minimum.
I shot some sunspots some time ago to give you an idea of what they look like here.
