Description

I captured these gorgeous active regions yesterday on our local star. These sunspots weren't there 4 days previously when I had observed. The Earth graphic is added at right to provide an accurate scale. Based on my own measurement and calculations, the full length of the bright plages, from end to end, was about 215,000 miles, or nearly the distance from the Earth to the Moon!
