Analysis of Solar Active Regions and Activity from 14/2100Z to 15/2100Z: Solar activity has been at very low levels for the past 24 hours. There are currently 1 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be very low with a slight chance for a C-class flare on days one, two, and three (16 Nov, 17 Nov, 18 Nov). IIA. Geophysical Activity Summary 14/2100Z to 15/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 422 km/s at 14/2101Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 1448 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on days one and two (16 Nov, 17 Nov) and quiet to unsettled levels on day three (18 Nov). III.
