Analysis of Solar Active Regions and Activity from 13/2100Z to 14/2100Z: Solar activity has been at very low levels for the past 24 hours. There are currently 2 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 (15 Oct, 16 Oct, 17 Oct). IIA. Geophysical Activity Summary 13/2100Z to 14/2100Z: The geomagnetic field has been at quiet to active levels for the past 24 hours. Solar wind speed reached a peak of 599 km/s at 14/2008Z. Total IMF reached 9 nT at 13/2102Z. The maximum southward component of Bz reached -6 nT at 13/2101Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 135 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on day one (15 Oct) and quiet levels on days two and three (16 Oct, 17 Oct). III.
