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 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 (11 Nov, 12 Nov, 13 Nov). IIA. Geophysical Activity Summary 09/2100Z to 10/2100Z: The geomagnetic field has been at quiet to active levels for the past 24 hours. Solar wind speed reached a peak of 604 km/s at 10/1332Z. Total IMF reached 13 nT at 10/0008Z. The maximum southward component of Bz reached -9 nT at 10/0814Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 1668 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on days one and two (11 Nov, 12 Nov) and quiet to unsettled levels on day three (13 Nov). III.
