Analysis of Solar Active Regions and Activity from 31/2100Z to 01/2100Z: Solar activity has been at low levels for the past 24 hours. There are currently 2 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 day one (02 Nov) and expected to be low with a chance for M-class flares and a slight chance for an X-class flare on days two and three (03 Nov, 04 Nov). IIA. Geophysical Activity Summary 31/2100Z to 01/2100Z: The geomagnetic field has been at unsettled levels for the past 24 hours. Solar wind speed reached a peak of 685 km/s at 31/2320Z. Total IMF reached 7 nT at 01/2030Z. The maximum southward component of Bz reached -5 nT at 01/2008Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 10573 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on days one and two (02 Nov, 03 Nov) and quiet to unsettled levels on day three (04 Nov). III.
