Turbulent region of the Sun turning Earthward

 http://sdo.gsfc.nasa.gov/data/aiahmi/browse/browse.php March 21, 2011 Here comes trouble? A big sunspot is emerging over the sun's southeastern limb, and it is crackling with activity. NASA's Solar Dynamics Observatory recorded a surge of extreme ultraviolet radiation from the sunspot's magnetic canopy on March 21st. This appears to be the return of old sunspot 1165, last seen in early March when it formed on the sun's southwestern limb. Since then it has been transiting the far side of the sun, apparently growing in size and restlessness. The potential for trouble will become more clear in the hours ahead as the active region emerges in full. Stay tuned. -Space Weather   |
