Sun’s Magnetic Field May Form Close to the Surface. This Finding Could Improve Solar Storm Forecasts

Deccan Chronicle  

CAPE CANAVERAL, Fla. — New research indicates the sun’s magnetic field originates much closer to the surface than previously thought, a finding that could help predict periods of extreme solar storms like the ones that slammed Earth earlier this month. The sun’s intense magnetic energy is the source of solar flares and eruptions of plasma known as coronal mass ejections. Solar flares and coronal mass ejections tend to occur near sunspots, dark patches as big as Earth that are located near the most intense portions of the sun’s shifting magnetic field. Vasil and his team developed new models of the interaction between the sun’s magnetic field and the flow of plasma, which varies at different latitudes during an 11-year cycle.
