SUMMARY: A massive flare erupted on the surface of the Sun yesterday that was so bright that it temporarily blinded the instruments on solar observation satellites. Astronomers believe this was the brightest flare that has ever been seen in modern times. Fortunately, this flare, and the following coronal mass ejection fired off to the side of the Sun, so very little material is expected to reach the Earth. The most powerful flares are the X-class; the most powerful flare ever seen before now was an X-20, but this could be an X-30, or even higher.
