Analysis of Solar Active Regions and Activity from 15/2100Z to 16/2100Z: Solar activity has been at low levels for the past 24 hours. The largest solar event of the period was a C1 event observed at 16/1606Z from Region 3123 (N27W68). There are currently 4 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 (17 Oct, 18 Oct, 19 Oct). IIA. Geophysical Activity Summary 15/2100Z to 16/2100Z: The geomagnetic field has been at quiet to active levels for the past 24 hours. Solar wind speed reached a peak of 606 km/s at 16/1309Z. Total IMF reached 7 nT at 15/2131Z. The maximum southward component of Bz reached -6 nT at 15/2101Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 808 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on day one (17 Oct) and quiet levels on days two and three (18 Oct, 19 Oct). III.
