Analysis of Solar Active Regions and Activity from 08/2100Z to 09/2100Z: 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 (10 Nov, 11 Nov, 12 Nov). IIA. Geophysical Activity Summary 08/2100Z to 09/2100Z: The geomagnetic field has been at unsettled to minor storm levels for the past 24 hours. Solar wind speed reached a peak of 623 km/s at 09/0016Z. Total IMF reached 7 nT at 08/2208Z. The maximum southward component of Bz reached -6 nT at 09/0550Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 20291 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at unsettled to minor storm levels on days one and two (10 Nov, 11 Nov) and quiet to active levels on day three (12 Nov). III.
