Analysis of Solar Active Regions and Activity from 24/2100Z to 25/2100Z: Solar activity has been at low levels for the past 24 hours. The largest solar event of the period was a C4 event observed at 25/1903Z from Region 3133 (N26E73). There are currently 5 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be very low with a chance for a C-class flares on days one, two, and three (26 Oct, 27 Oct, 28 Oct). IIA. Geophysical Activity Summary 24/2100Z to 25/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 497 km/s at 24/2109Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 269 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on day one (26 Oct), quiet to unsettled levels on day two (27 Oct) and quiet to active levels on day three (28 Oct).
