3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 26/2100Z to 27/2100Z: The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed reached a peak of 546 km/s at 27/1001Z. Total IMF reached 16 nT at 27/0612Z. The maximum southward component of Bz reached -9 nT at 26/2141Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 153 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on day one (28 Apr) and quiet to unsettled levels on days two and three (29 Apr, 30 Apr).
Solar ActivityAnalysis of Solar Active Regions and Activity from 26/2100Z to 27/2100Z: Solar activity has been at moderate levels for the past 24 hours. The largest solar event of the period was a M2 event observed at 27/1235Z from Region 3654 (S08W23). There are currently 9 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be low with a chance for M-class flares on days one, two, and three (28 Apr, 29 Apr, 30 Apr).
