STEREO Satellites Spot Solar Flare Tsunami

Posted by CmdrTaco on from the gonna-need-more-spf dept.

westtxfun writes "The STEREO satellites recently confirmed the existence of solar mega-tsunamis when they captured height data after a sunspot recently erupted. The scale of this tsunami literally dwarfs the Earth's diameter — it was 62,000 miles high and raced across the surface at 560,000 mph! STEREO A and B orbit 90 degrees apart and luckily, one was overhead while the other saw the eruption on the limb. This gave NASA scientists enough data to confirm the tsunami wasn't a shadow, solving a modern solar mystery. The images are simply stunning, to boot."

  1. Large CME? by IGnatius+T+Foobar · · Score: 3, Interesting

    Wait a minute. Wasn't a CME this big supposed to completely destroy the power grid? Wasn't this supposed to plunge us back into the stone age?

    So what happened?
