SOHO image caption: These three images show the evolution of the coronal mass ejection from March 8, 11:38 PM EST to March 9, 12:53 AM EST as captured by the Solar Heliospheric Observatory (SOHO). The sun is obscured in this image, called a coronograph, so that the dim atmosphere — or corona — around the sun can be better seen. The white speckles on the image are “noise” from solar particles hitting the instrument. Credit: SOHO/ESA & NASA

On March 8, 2012 at 10:53 PM EST it erupted with an M6.3 class flare, and about an hour later released a CME. In addition to today’s rising geomagnetic storm conditions, active region 1429 that has so far produced two X class flares, and numerous M-class flares continues to crackle.
NASA’s Space Weather Center models measure the CME traveling at speeds of over 700 miles per second. The CME should reach Earth’s magnetosphere, the protective envelope of magnetic fields around the planet, early in the morning of March 11.
