[NLRS] Space WX -- CME report

[Bill Davis via NLRS]

CME IMPACT, SEVERE GEOMAGNETIC STORM: Arriving earlier than expected, a CME hit Earth's magnetic field on March 17th at approximately 04:30 UT. At first, the impact sparked a relatively mild G1-class (Kp=5) geomagnetic storm confined to the poles. Since then, however, the storm has intensified to G4-class (Kp=8), ranking it as the strongest geomagnetic storm of the current solar cycle.
