IA. Analysis of Solar Active Regions and Activity from 01/2100Z to 02/2100Z: Solar activity has been at low levels for the past 24 hours.

The largest solar event of the period was a C2 event observed at 02/0214Z from Region 3135 (N26E00). There are currently 4 numbered sunspot regions on the disk.

IB. Solar Activity Forecast: Solar activity is likely to be low with a slight chance for an M-class flare on days one, two, and three (03 Nov, 04 Nov, 05 Nov).

IIA. Geophysical Activity Summary 01/2100Z to 02/2100Z: The geomagnetic field has been at quiet to active levels for the past 24 hours. Solar wind speed reached a peak of 544 km/s at 02/2045Z. Total IMF reached 9 nT at 02/1647Z. The maximum southward component of Bz reached -9 nT at 02/1833Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 6466 pfu.

IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on day one (03 Nov), quiet to unsettled levels on day two (04 Nov) and quiet to minor storm levels on day three (05 Nov).
