Impulsive M1.2 solar flare erupted from Region 1686
An impulsive M-class solar flare measuring M1.2 erupted from Region 1686 on March 5, 2013. The event started at 07:47, peaked at 07:54 and ended at 07:59 UTC. A Type II Radio Emission was associated. Type II emissions occur in association with eruptions on the Sun and typically indicate a Coronal Mass Ejection is associated with a flare event. Region 1686 has Beta magnetic configuration.

Beta classified Region 1682 is rotating onto the southwest limb, Region 1686 is following. Other than that, we have 4 more Beta classified regions about to become geoeffective. Regions 1683, 1685, 1687 and 1689 are visible on the image below:

do you suppose that one of these or bigger could cause a CME that could not only cripple our electrical but harm us as well? What are the chances? Do we understand enough? I mean this has gone on for years and years and yes only now we have such technologies to watch the sun but other than 1859 and was it 1993, could we really be facing something damaging or crippling in any way that we need to worry? After all, there are some scientist who claim aluminum foil wrapping out electronics will save it from any CME. Really?
