Analysis of Solar Active Regions and Activity from 02/2100Z to 03/2100Z: 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 03/0132Z from Region 3480 (S11E64). There are currently 7 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 (04 Nov, 05 Nov, 06 Nov). IIA. Geophysical Activity Summary 02/2100Z to 03/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 506 km/s at 03/0844Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 2847 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on day one (04 Nov) and quiet to active levels on days two and three (05 Nov, 06 Nov). III.
