Sol


In this handout photo released by Nasa Earth Observatory on June 7, 2011 and taken from Nasa's Solar Dynamics Observatory, sunspot complex 1226-1227, shows the Sun unleashing an M-2 (medium-sized) solar flare, an S1-class radiation storm and a coronal mass ejection resulting in a large cloud of particles mushrooming up and falling back down giving the impression of covering an area of almost half the solar surface. An unusual solar flare observed by a NASA space observatory on June 7 could cause some disruptions to satellite communications and power on Earth over the next day or so, officials said.
