3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 18/2100Z to 19/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 521 km/s at 18/2146Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 5020 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on day one (20 Sep), quiet to active levels on day two (21 Sep) and unsettled to minor storm levels on day three (22 Sep).
Solar ActivityAnalysis of Solar Active Regions and Activity from 18/2100Z to 19/2100Z: Solar activity has been at low levels for the past 24 hours. 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 (20 Sep, 21 Sep, 22 Sep).
