Analysis of Solar Active Regions and Activity from 09/2100Z to 10/2100Z: Solar activity has been at very low levels for the past 24 hours. There are currently 3 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be very low with a chance for a C-class flares on days one, two, and three (11 Nov, 12 Nov, 13 Nov). IIA. Geophysical Activity Summary 09/2100Z to 10/2100Z: The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed reached a peak of 469 km/s at 10/1553Z. Total IMF reached 6 nT at 09/2201Z. The maximum southward component of Bz reached -6 nT at 09/2157Z. Protons greater than 10 MeV at geosynchronous orbit reached a peak level of 2 pfu at 09/2125Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 1711 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on days one, two, and three (11 Nov, 12 Nov, 13 Nov). III.
