Sun unleashes most powerful flare seen in 4 years

February 15, 2011FIRST X-FLARE OF THE NEW SOLAR CYCLE: Sunspot 1158 has unleashed the strongest solar flare in more than four years. The eruption, which peaked at 0156 UT on Feb. 15th, registered X2 on the Richter scale of solar flares. NASA’s Solar Dynamics Observatory recorded an intense flash of extreme ultraviolet radiation, circled above. X-flares are the strongest type of solar flare, and this is the first such eruption of new Solar Cycle 24. In addition to flashing Earth with UV radiation, the explosion also hurled a coronal mass ejection (CME) in our direction. Geomagnetic storms are possible when the CME arrives 36 to 48 hours hence. Stay tuned for updates. –Space Weather

    “Nasa warns solar flares from ‘huge space storm’ will cause devastation
    Britain could face widespread power blackouts and be left without critical communication signals for long periods of time, after the earth is hit by a once-in-a-generation ‘space storm’, Nasa has warned.”

    Senior space agency scientists believe the Earth will be hit with unprecedented levels of magnetic energy from solar flares after the Sun wakes ‘from a deep slumber’
