Solar storm

If you follow this blog at all, you know that I am an avid solar observer - and yesterday the Solar Dynamics Observatory captured a massive eruption on the sun.  According to the mission blog "The Sun unleashed an M-2 (medium-sized) solar flare with a spectacular coronal mass ejection (CME) on June 7. The large cloud of particles mushroomed up and fell back down looking as if it covered an area of almost half the solar surface.

SDO observed the flare's peak at 1:41 AM ET. SDO recorded these images in extreme ultraviolet light and they show a very large explosion 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 80,000K.

When viewed in SOHO's coronagraphs, the event shows bright plasma and high-energy particles roaring from the Sun. This Earth-directed CME is moving at 1400 km/s according to NASA models. Due to its angle, however, effects on Earth should be fairly small. Nevertheless, it may generate space weather effects here on Earth in a few days."  This video is unlike any that has previously been recorded:
