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 656 km/s at 26/1743Z. Total IMF reached 5 nT at 26/0745Z. The maximum southward component of Bz reached -4 nT at 26/1448Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 1636 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on days one and two (27 Jun, 28 Jun) and quiet levels on day three (29 Jun).
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 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 (27 Jun, 28 Jun, 29 Jun).
