Turbulent region of the Sun with coronal hole turns Earthward

February 26, 2011EASTERN SUNSPOTS: The northeastern limb of the sun is peppered with sunspots, photographed during the early hours of Feb. 26th by NASA’s Solar Dynamics Observatory. On Feb. 24th, the scatter of small spots in the foreground unleashed a spectacular M3-class solar flare. How did such a puny group of spots produce such a potent explosion? The region has a complex “beta-gamma” magnetic field that harbors energy for strong flares. It’s actually more likely to produce explosions than the larger yet simpler sunspot above and behind it. NOAA forecasters estimate a 50% chance of more M-flares during the next 24 hours. – Space Weather

    Hi! Alvin…what does it mean when the Magnetosphere twists like this in the planetary sphere? Thanx!

    • In the simplest explanation possible, this has to do with characteristic behavior of the nature of plasma and electromagnetic fields. The planet’s magnetic field oscillates between repulsion during a flare and magnetic reconnection which is an energy transference process. The twisting is part of the reconnection process. Magnetic reconnection in Earth’s magnetosphere is one of the mechanisms responsible for the effects of auroras.
