Watch the Biggest Sunspot in 24 Years Traverse the Sun

You're looking at the largest sunspot since 1990 as it crossed the surface of the Sun. Captured between October 17th and 29th, the spot was big enough to see without a telescope.

Despite its size and production of lots of flares, it "did not produce any significant coronal mass ejections (CME)", according to Alex Young a solar scientist at NASA's Goddard Space Flight Center. A CME is a huge solar flare that sends out massive amounts of electromagnetic radiation, which could potentially effect Earth's magnetosphere. [NASA]
