Explanation: Right now, one of the largest sunspot groups in recent history is crossing the Sun. Active Region 3664 is not only big -- it's violent, throwing off clouds of particles into the Solar System. Some of these CMEs are already impacting the Earth, and others might follow. At the extreme, these solar storms could cause some Earth-orbiting satellites to malfunction, the Earth's atmosphere to slightly distort, and electrical power grids to surge. When impacting Earth's upper atmosphere, these particles can produce beautiful auroras, with some auroras already being reported unusually far south. Pictured here, AR3664 and its dark sunspots were captured yesterday in visible light from Rome, Italy. The AR3664 sunspot group is so large that it is visible just with glasses designed to view last month's total solar eclipse. This weekend, skygazing enthusiasts will be keenly watching the night skies all over the globe for bright and unusual auroras.

You can use a telescope in reverse to project the sun’s image on the ground. I did this for a school group for the eclipse.
Took a scope for the 100-yard line at the range for that.
Go right near the edge of the roof and place scope on tripod just into the sun, and project the image just into the shade made by the roof edge.

Ha! I actually shot some pictures of it with my .telescope and iPhone. I would like to post them, but I’m all thumbs with picture posting. I just took everything apart and put it away. I’m pooped. No spring chicken here…..🙂

I’ve been following it for the past couple of days as it heads toward the limb.

It requires a third-party host to post photos here, IIRC.
