The Northern Lights will possibly be visible down to Idaho and Montana's latitude on Jan. 24 and 25.

The strongest Solar Radiation Storm since December 2006 is in progress and continues to get stronger and a very fast Coronal Mass Ejection (CME) is headed towards Earth. Geomagnetic storming is a near certainty from this event, but pending preliminary analysis, no estimates are available yet for timing or strength of the storm.

The associated solar flare peaked at the R2 (Moderate) level on January 23 at 0400 GMT (11pm Jan 22 EST). Radiation storms are a concern for astronauts, for communications at high latitudes, for satellites in space and for many rockets being launched.

We will keep you posted. In the meantime, you can follow the radiation storm at So long as the red trace is above the dashed line, we are at alert levels. The attached photo shows the event still rising at this time.
