IA. Analysis of Solar Active Regions and Activity from 31/2100Z to 01/2100Z: Solar activity has been at very low levels for the past 24 hours. There are currently 0 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be very low 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 levels for the past 24 hours. Solar wind speed reached a peak of 307 km/s at 01/1601Z. Total IMF reached 10 nT at 01/1731Z. The maximum southward component of Bz reached -5 nT at 01/1905Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 2866 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on day one (02 Nov), quiet to unsettled levels on day two (03 Nov) and quiet levels on day three (04 Nov).
