There remains a 70 percent chance of more M-class flares, and a 15 percent chance of even more disruptive X-class flares Tuesday.
A solar flare is an explosion where twisted magnetic fields let loose their energy from the surface of the sun. These are often above sunspots large enough to swallow the entire Earth. The flares contain X-rays, gamma rays, and other electromagnetic radiation, capable of producing various effects on the skies and technology on earth.READ MORE: KPIX Original Report: SF Mission Bay Sidewalks Sinking But City Won't Fix 'Private Property'
They are classified as X-Class, or very big flares that can plunge the entire planet into radio blackouts. The next class is M-class, which are medium-sized, and primarily affect radio communication around the poles. s here on Earth.Twitter To Pay $809 Million To Settle Class Action Lawsuit Brought By Investors
