Analysis of Solar Active Regions and Activity from 22/2100Z to 23/2100Z: Solar activity has been at low levels for the past 24 hours. There are currently 8 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be low with a slight chance for an M-class flare on days one, two, and three (24 Oct, 25 Oct, 26 Oct). IIA. Geophysical Activity Summary 22/2100Z to 23/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 501 km/s at 23/2001Z. Total IMF reached 10 nT at 23/0950Z. The maximum southward component of Bz reached -7 nT at 23/1647Z. Protons greater than 10 MeV at geosynchronous orbit reached a peak level of 2 pfu at 23/0000Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 681 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on days one and three (24 Oct, 26 Oct) and quiet to unsettled levels on day two (25 Oct). III.
