G3 (Strong) Geomagnetic Storm Underway

As of 7:30 pm Eastern Daylight Time, a coronal mass ejection, produced by an X1.6 flare 2 days ago, struck the earth.

The resulting geomagnetic storm is currently a G3 (strong intensity), which can cause power grid fluctuations, voltage alarms in high-latitude power systems, and possible transformer damage if the storm is of long duration. Electrical systems may require voltage correction, and false alarms may be triggered on some protection devices.

However, there is a slight possibility it may rise as high as a G4, which can potentially cause "widespread voltage control problems" and "some protective systems will mistakenly trip out key assets from the grid", which could mean localized blackouts or rolling brownouts.

While I do not feel we are in any danger from this, now would be a good time to check your preps. Make sure you have plenty of water on standby and that your flashlights have fresh batteries. 

Check the Space Weather Prediction Center for more information as the situation progresses.
