IA. Analysis of Solar Active Regions and Activity from 09/2100Z to 10/2100Z: Solar activity has been at low levels for the past 24 hours. The largest solar event of the period was a C2 event observed at 10/1119Z from Region 3100 (S25E48). There are currently 8 numbered sunspot regions on the disk.

IB. Solar Activity Forecast: Solar activity is likely to be low with a slight chance for an M-class flare on days one, two, and three (11 Sep, 12 Sep, 13 Sep).

IIA. Geophysical Activity Summary 09/2100Z to 10/2100Z: The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed reached a peak of 518 km/s at 10/2053Z. Total IMF reached 6 nT at 10/1700Z. The maximum southward component of Bz reached -6 nT at 10/0527Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 15502 pfu.

IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on days one and three (11 Sep, 13 Sep) and quiet levels on day two (12 Sep).
