Geomagnetic fall to earth

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.

Geomagnetic storm
A geomagnetic storm is a temporary disturbance of the Earth's magnetosphere caused by a disturbance in the interplanetary medium. A geomagnetic storm is a major component of space weather and provides the input for many other components of space weather. A geomagnetic storm is caused by a solar wind shock wave and/or cloud of magnetic field which interacts with the Earth's magnetic field.
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.
