Sunspots AR1520 AR1519 and AR1514

Sunspots AR1520 AR1519 and AR1514

At the Strawberry Festival today a series of sunspots were visible. Probably the most spectacular was AR1520 which stretches 10 Earth diameters from end to end, more than 127,000 km. Nearby AR1519 was dwarfed by it. On another edge you could see AR1514. The Baader Solar Film that I was using produces images of remarkable detail, surface granulation is readily seen.
