CME Approaching Earth; Radio Disruptions Expected

The Coronal Mass Ejection (CME) that was emitted from the sun due to an X-Class flare is closing in on Earth, as the ACE spacecraft (1 million miles from Earth) that measures solar indices detected a significant spike in wind and temperature around 12:30 PM CDT this afternoon.

At this time, a geomagnetic storm of 'G1' strength is forecast to occur in the next 24 hours per the Space Weather Prediction Center (SWPC). 'G1' strength is defined by weak power grid fluctuations and changes in some migratory patterns of animals. The Space Weather Prediction Center does indicate that 'G2' solar storm strength is possible. This would show up as power issues among high latitude locations, as well as radio disruptions and potential issues to spacecraft orbit tracks.

No significant human health impact is likely from this geomagnetic storm. Any issues would likely be due to hospital patients losing access to some equipment due to potential power issues, but that is on the unlikely side.
