NEW SUNSPOT: Breaking
a string of two spotless days, new sunspot AR2665 is emerging over
the sun's eastern limb. It's a big sunspot, with a primary dark core
twice as wide as Earth. The magnetic canopy of AR2665 is crackling
with minor B-class solar flares, but so far nothing stronger. This is probably a mostly-quiet sunspot typical of the decaying solar cycle. Free: Solar Flare Alerts

wind into space. NASA's Solar Dynamics Observatory is monitoring the
structure as it turns to face Earth:
