Surprise Geomagnetic Storm – Flash Traffic

This was unexpected. The Earth experienced a strong, level three geomagnetic storm last night, jacking up the KP Index to a level 7. NOAA, NASA, the ESA and IPS in Australia all failed to predict this. The reason this was so unusual is that the solar wind speed peaked at only around 500 kps, which is stronger than ambient solar wind but much weaker than a typical CME (coronal mass ejection). In other words, there is nothing in the history of studying these events to suggest that a mild CME from the eruption of a small plasma filament, that barely hit the Earth with a glancing blow would produce such a strong geomagnetic storm. Now, although a level 7 KP reading isn’t necessarily worrisome in terms of a solar kill-shot, there aren’t many possible explanations for such a strong storm from such a small CME.

So, what does this mean?

As many know, the Earth’s magnetic field has been weakening significantly. In 2000 is had lost 10% of it’s strength since the 1800’s, another 5% was lost by 2010, and we know that further losses were measured in 2015 and 2017. What this event suggests is that it may actually be much weaker than we realize. This makes the Earth extremely susceptible to future solar storms, and we are now entering solar cycle 25, with sunspots and space weather ramping up to a peak in 2025. The risk to the grid, and thus our way of life (electricity) is considerable.

So, we’ll ask again: What are YOU preparing for?
