3-day Solar-Geophysical Forecast
Geophysical Activity	Geophysical Activity Summary 26/2100Z to 27/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 274 km/s at 27/0133 UTC. Total IMF reached 5 nT at 27/1953 UTC. The maximum southward component of Bz reached 1 nT at 27/0846 UTC. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 1732 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to major storm levels on days one and two (28 Aug, 29 Aug) and quiet to active levels on day three (30 Aug). Protons have a slight chance of crossing threshold on days one, two, and three (28 Aug, 29 Aug, 30 Aug).
Solar Activity	Analysis of Solar Active Regions and Activity from 26/2100Z to 27/2100Z: Solar activity has been at low levels for the past 24 hours. There are currently 5 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be low with a chance for M-class flares and a slight chance for an X-class flare on days one, two, and three (28 Aug, 29 Aug, 30 Aug).
