IA. Analysis of Solar Active Regions and Activity from 05-2100Z to 06-2100Z

Solar activity has been at high levels for the past 24 hours. The largest solar event of the period was a M5 event observed at 06/0346Z from Region 2205 (N15E46). There are currently 6 numbered sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is likely to be moderate with a chance for X-class flares on days one, two, and three (07 Nov, 08 Nov, 09 Nov).
IIA. Geophysical Activity Summary 05-2100Z to 06-2100Z
The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed, as measured by the ACE spacecraft, reached a peak speed of 575 km/s at 05/2123Z. Total IMF reached 6 nT at 06/1137Z. The maximum southward component of Bz reached -6 nT at 06/2047Z.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to unsettled levels on days one, two, and three (07 Nov, 08 Nov, 09 Nov). Protons have a slight chance of crossing threshold on days one, two, and three (07 Nov, 08 Nov, 09 Nov).
