IA.  Analysis of Solar Active Regions and Activity from 10/2100Z to 11/2100Z: Solar activity has been at very low levels for the past 4 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 (12 Nov, 13 Nov, 14 Nov).

IIA.  Geophysical Activity Summary 10/2100Z to 11/2100Z: The geomagnetic field has been at quiet to active levels for the past 24 hous. Solar wind speed reached a peak of 624 km/s at 10/2313Z. Total IMF reached 6 nT at 11/2041Z. The maximum southward component of Bz eaced -5 nT at 11/1841Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 1341 pfu.
