Sun news: Flare forecast is promising

The biggest activity this past week was on the far side of the sun. It was a massive eruption, strong enough to send a wave around the sun and high-energy particles to Earth (heliophysicist C. Alex Young gave a great explanation of that wave and the particle storm on Friday's livestream). Now a new sunspot region with an interesting magnetic complexity (currently beta-gamma-delta) has rotated into view. It's labeled AR3906. Read the sun news.
