NOAA SEC Space Weather Advisory Bulletin #06-5: Geomagnetic Storm in Progress

Joint USAF/NOAA Report of Solar and Geophysical Activity 13 Dec 2006

“Geophysical Activity Forecast: The geomagnetic field is expected to reach major to severe storm levels. Activity from the CME observed early on 13 December is expected to impact the geomagnetic field by mid to late UTC on day 1 (14 December) of the forecast period. Major to severe storm conditions are expected to continue early into 15 December. Levels should decrease to unsettled to minor storming by 16 December. The greater than 100 MeV and 10 MeV proton events now in progress are expected to continue for the next 24 to 48 hours.”
