You know a #sunspot is big when you can see it in the #sunset. At the end of the day on Oct. 5th, Radu Anghel photographed AR3112 from #Bacau, #Romania:

"What a wonderful view," says Anghel. "Clouds crossing the solar disk made it look like a big Jupiter with sunspots! :)"

AR3112 is one of the biggest sunspots in years. With more than a dozen dark cores scattered across 300,000 km of solar terrain
