3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 24/2100Z to 25/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 350 km/s at 25/1357Z. Total IMF reached 6 nT at 25/1407Z. The maximum southward component of Bz reached -4 nT at 25/08414Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 1670 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at unsettled to active levels on day one (26 Apr) and quiet to active levels on days two and three (27 Apr, 28 Apr). Protons have a slight chance of crossing threshold on days one, two, and three (26 Apr, 27 Apr, 28 Apr).
Solar ActivityAnalysis of Solar Active Regions and Activity from 24/2100Z to 25/2100Z: Solar activity has been at moderate levels for the past 24 hours. The largest solar event of the period was an M1.1 event observed at 25/1712Z from Region 3638 (S18, L=231). There are currently 13 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 (26 Apr, 27 Apr, 28 Apr).
