IA. Analysis of Solar Active Regions and Activity from 25/2100Z to 26/2100Z: Solar activity has been at high levels for the past 24 hours. The largest solar event of the period was a M7 event observed at 26/0315Z from Region 3938 (N21E40). There are currently 11 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be moderate with a slight chance for an X-class flare on days one, two, and three (27 Dec, 28 Dec, 29 Dec). IIA. Geophysical Activity Summary 25/2100Z to 26/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 454 km/s at 25/2146Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 867 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on day one (27 Dec), quiet to unsettled levels on day two (28 Dec) and quiet levels on day three (29 Dec). Protons have a slight chance of crossing threshold on days one, two, and three (27 Dec, 28 Dec, 29 Dec).
