2 (medium-sized) solar 1, an s1-class (minor) radiation storm and a spectacular coronal（冠状物） mass ejection (cme) on june 7, 2011 from sunspot complex 1226-1227. the large cloud of particles mushroomed up and fell back down looking as if it covered an area of almost half the solar surface. the solar 2 3 (sdo) observed the flare's peak at 1:41a.m. et (0641 ut). sdo recorded these images (above) in extreme ultraviolet light that show a very large 4 of cool gas. it is somewhat unique because at many places in the eruption there seems to be even cooler material -- at temperatures less than 80,000 k.
when viewed in solar and heliospheric observatory's (soho) coronagraphs（日冕仪） (right), the event shows bright 5 and high-energy particles roaring from the sun. this not-squarely earth-directed cme is moving at 1400 km/s according to nasa models.
the cme should deliver a glancing blow to earth's magnetic field during the late hours of june 8th or june 9th. high-latitude sky watchers should be alert for auroras（极光） when the cme arrives.
