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 6 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 and two (30 Oct, 31 Oct) and likely to be low with a slight chance for an M-class flare on day three (01 Nov). IIA. Geophysical Activity Summary 28/2100Z to 29/2100Z: The geomagnetic field has been at unsettled to active levels for the past 24 hours. Solar wind speed reached a peak of 607 km/s at 29/1605Z. Total IMF reached 13 nT at 29/0029Z. The maximum southward component of Bz reached -11 nT at 28/2132Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 333 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at unsettled to minor storm levels on day one (30 Oct), unsettled to active levels on day two (31 Oct) and quiet to unsettled levels on day three (01 Nov).
