2013-05-18 14:35 UTC  Watching for CME Passage May 19

Having felt the effects of the first CME earlier today, Forecasters now watch for another, stronger pulse. They are anticipating the passage of a CME that left the Sun May 17 around 1400 UTC (10 a.m. EDT) on May 19.  Their prediction is for Geomagnetic Storm category G2 (Moderate) activity to follow over the next 24 hours, persisting into May 20. The current Solar Radiation Storm is expected to stay at category S1 (Minor), although the proton flux may increase slightly with the passage of the shock driven by the CME. Updates here.
