AR11520 - Solar Seas of Plasma - 11th july

Only the briefest of cloud gaps this afternoon allowed me to setup and then record this image: Monster active region AR11520 still has a delta class magnetic field and is more than capable of producing x-class flares, however has remained fairly quiet in the last 24 hours. In the mean time rivers of solar plasma readily flow like rivers in and around its component spots. Any flare activity now is squarely geo-effective as this maelstrom sits mid disk on our star, and so the risk of a storm is considerably higher...
