4th of July Sunspots

Looks like there's a nice sunspot group on the Sun -- some nice solar fireworks for the 4th of July! Biggest group I've seen in quite sometime. It is right on the meridian.

Note a group of small sunspots have just come onto the disk. They're not visible to the naked eye but might be nice with a white light or H-alpha filter.
