    I'm sorry, what are you referring to? I've never heard of a geomagnetic.

    Maybe he is referring to the geomagnetic storm that was caused by a solar coronal mass ejection and caused the aurora borealis on January 24?

    Here is an excerpt from an article that explains it in detail.

    Timacho, please note that the geomagnetic storm does not produce a solar storm. Quite the opposite. The geomagnetic storm itself is caused by solar activity. It is
    called "geomagnetic" [geo=earth] because it is triggered when the solar wind interacts with earth's magnetic field.
