Analysis of Solar Active Regions and Activity from 31/2100Z to 01/2100Z: Solar activity has been at moderate levels for the past 24 hours. The largest solar event of the period was a M1 event observed at 01/1226Z. There are currently 6 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 (02 Nov, 03 Nov, 04 Nov). IIA. Geophysical Activity Summary 31/2100Z to 01/2100Z: The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed reached a peak of 523 km/s at 31/2148Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 2117 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on days one and three (02 Nov, 04 Nov) and quiet levels on day two (03 Nov). III.
