3-day Solar-Geophysical Forecast
Geophysical Activity	Geophysical Activity Summary 28/2100Z to 29/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 420 km/s at 28/2147Z. Total IMF reached 6 nT at 29/0011Z. The maximum southward component of Bz reached -4 nT at 29/0158Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 1228 pfu at 29/1630Z. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on day one (30 Oct), unsettled to minor storm levels on day two (31 Oct) and quiet to minor storm levels on day three (01 Nov).
Solar Activity	Analysis of Solar Active Regions and Activity from 28/2100Z to 29/2100Z: 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 (30 Oct, 31 Oct, 01 Nov).
