Sunspot is Back and Worse than Ever

November 13, 2014 7:00 am | by The Conversation, Paul Cally | Videos | Comments

The largest sunspot seen in 24 years is rotating back to face the Earth, and it looks to have grown even bigger. Last month, the solar active region known as AR12192 entertained the world with the sunspot clearly visible to the naked eye as it produced a series of large flares. But, after spending some time over on the far side of the sun, it hasn’t finished impressing us yet.
