CME SPARKS GEOMAGNETIC STORM: As predicted, a CME hit Earth’s magnetic field today, March 13th, sparking a moderately-strong G2-class geomagnetic storm. Depending on conditions in the CME’s wake, the storm could spill into March 14th. If it does, sky watchers in northern-tier US states might be able to see auroras after local nightfall.
