The Sun Unleashes Coronal Mass Ejection At Earth

astroengine writes "Yesterday morning, at 08:55 UT, NASA's Solar Dynamics Observatory detected a C3-class flare erupt inside a sunspot cluster. 100,000 kilometers away, deep within the solar atmosphere (the corona), an extended magnetic field filled with cool plasma forming a dark ribbon across the face of the sun (a feature known as a 'filament') erupted at the exact same time. It seems very likely that both eruptions were connected after a powerful shock wave produced by the flare destabilized the filament, causing the eruption. A second solar observatory, the Solar and Heliospheric Observatory, then spotted a huge coronal mass ejection blast into space, straight in the direction of Earth. Solar physicists have calculated that this magnetic bubble filled with energetic particles should hit Earth on August 3, so look out for some intense aurorae — a solar storm is coming."

      Going by the values on Wikipedia and NASA's GOES web site, a C3 CME is a total influx of about 3 micro-watts per square meter. For reference, normal solar insolation is about 360 watts per square meter. So, the answer to your rhetorical statement is, "Yes, this is being massively overhyped, because the sun hasn't done diddly squat over the last five years and someone has to justify paying billions of dollars for solar observing satellites."

      Before anyone gets all pissy... yes, the CME comes in the form of energized protons and pico-wave X-Rays, so they are more destructive to human tissue than normal sunlight. But given that the Earth survived a Y+ level (1000-10,000 times more powerful) in 1859 with no one keeling over dead, I think we're safe.
