One of the most powerful solar flares ever recorded (an X14-class explosion) erupted near sunspot group 9415 today, climaxing a two-week spate of X-class flares from that active region. The source of the explosion is near the Sun's western limb, so the blast was directed mostly away from Earth. That's a good thing because today's flare was nearly as powerful as one in 1989 that triggered the collapse of a power grid in Canada -- no such calamities are expected this time. A moderate radiation storm is in progress. For details and updates, please visit SpaceWeather.com.
