3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 04/2100Z to 05/2100Z: The geomagnetic field has been at unsettled to active levels for the past 24 hours. Solar wind speed reached a peak of 782 km/s at 05/0241Z. Total IMF reached 8 nT at 05/1652Z. The maximum southward component of Bz reached -8 nT at 05/1707Z. Protons greater than 10 MeV at geosynchronous orbit reached a peak level of 20 pfu at 05/0055Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 1067 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to minor storm levels on day one (06 Jan), quiet to active levels on day two (07 Jan) and quiet to unsettled levels on day three (08 Jan). Protons have a chance of crossing threshold on day one (06 Jan) and have a slight chance of crossing threshold on days two and three (07 Jan, 08 Jan).
Solar ActivityAnalysis of Solar Active Regions and Activity from 04/2100Z to 05/2100Z: Solar activity has been at high levels for the past 24 hours. The largest solar event of the period was a M4 event observed at 05/0239Z from Region 3947 (N11E29). There are currently 12 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be moderate with a chance for X-class flares on days one and two (06 Jan, 07 Jan) and likely to be moderate with a slight chance for an X-class flare on day three (08 Jan).
