Analysis of Solar Active Regions and Activity from 08/2100Z to 09/2100Z: Solar activity has been at very low levels for the past 24 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 (10 Oct, 11 Oct, 12 Oct). IIA. Geophysical Activity Summary 08/2100Z to 09/2100Z: The geomagnetic field has been at quiet to active levels for the past 24 hours. Solar wind speed reached a peak of 477 km/s at 09/0649Z. Total IMF reached 11 nT at 09/2039Z. The maximum southward component of Bz reached -7 nT at 09/0738Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 459 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on days one, two, and three (10 Oct, 11 Oct, 12 Oct). III.
