A large coronal mass ejection (CME) has reached Earth. The CME that stroke the Earth has been associated with the large X1.2-class solar flare that was unleashed from a giant sunspot AR1944 on January 7. The flare has been described as the most powerful this year so far, with X-class denoting the most severe intensity.
NOAA’s Space Weather Prediction Center has issued a warning of a geomagnetic storm with “minor disruptions to communications and GPS.”
