Check out an active sunspot on the Sun today! The dark sunspot seen at right produced a moderate solar flare early Tuesday morning. The bright area around it, called a plage, is a cloud of gas heated by solar activity like solar flares. This live, close-up view of the Suns atmosphere comes from a calcium-K telescope at the Phoebe Waterman Haas Public Observatory. The live view will be available until 3 pm EDT, weather permitting.
