3-day Solar-Geophysical Forecast
Geophysical Activity	Geophysical Activity Summary 25/2100Z to 26/2100Z: The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed reached a peak of 459 km/s at 26/1918Z. Total IMF reached 9 nT at 26/1838Z. The maximum southward component of Bz reached -7 nT at 26/2021Z. Protons greater than 10 MeV at geosynchronous orbit reached a peak level of 23 pfu at 26/0110Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 455 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on days one and two (27 May, 28 May) and quiet levels on day three (29 May). Protons greater than 10 Mev have a slight chance of crossing threshold on day one (27 May).
Solar Activity	Analysis of Solar Active Regions and Activity from 25/2100Z to 26/2100Z: 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 (27 May, 28 May, 29 May).
