Sunspots of Interest



Sunspots of Interest
The sunspot number is rising as a pair of new active regions emerges over the sun's eastern limb. Click to view a 48 hour movie from NASA's Solar Dynamics Observatory [you may have to go to the web page to do this]:

Three of the six sunspot groups now facing Earth have 'beta-gamma' magnetic fields that harbor energy for M-class solar flares. Of particular interest is AR2222 (circled). Having tripled in size since it appeared two days ago, it seems more likely to erupt than any of the others. NOAA forecasters estimate a 30% chance of M-flares on Nov. 28th.
