Solar Flare Today: 2014 CME Hits Earth, Aurora Borealis Expected on Jan 9, 10

    A solar flare from the sun that was headed to Earth hit today around 3 p.m. EST, arriving weaker than expected.

    The intial weak impact could strengthen, though, as geomagnetic storms could develop as Earth passes through the coronal mass ejection (CME)’s wake, according to Space Weather.

    NASA forecasters are predicting a strong geomagnetic storm Thursday and Friday, with possible widespread voltage control problems.

    The X1.2-class solar flare on January 7 was associated with the CME, a solar phenomenon that can send billions of tons of particles into space, which sometimes reach Earth one to three days later.

    “These particles cannot travel through the atmosphere to harm humans on Earth, but they can affect electronic systems in satellites and on the ground,” according to NASA. They are particularly harmful to small, modern electronics.

    X-class flares are the most intense flares, with X1-class being the lowest in intensity scale. An X2 flare is twice as intense as X1, and so on.

    The flare is expected to bring an aurora, a phenomenon that brings lights from the sky, across the United States on Thursday and Friday nights, the National Weather Center said.

    “If you don’t mind getting up early and have few to no clouds in your area overnight, you may get a chance to see the Aurora if you live in the Northern lower 48,” it said.

      I want to be here when science learns how to harvest CMEs and convert the energy into powering life on Earth as well as expanding humanity out to the rest of the solar system.

        That would be quite an accomplishment. Not sure I can envision a stand-alone tec (storage) but rather an add-on to existing grid (immediate dispersal.) “Inverted / converted” on-the-fly; power down natural-resource-eating generators. Not a total win-win but still quite an assist.

          I envision something that looks and acts a lot like hydroelectric, except instead of water, it’d be plasma. Funneled and cycled along by magnetic fields that are powered by the CME itself.

      I had a Big Migraine this week for 4 days and I’m not prone to them. Today was the first day of no headache. I read many people feel effects of solar flares, like body aches, communication issues, trouble thinking etc.. I guess it landed already or weakened.
