Analysis of Solar Active Regions and Activity from 23/2100Z to 24/2100Z: Solar activity has been at moderate levels for the past 24 hours. There are currently 10 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be low with a chance for M-class flares on days one, two, and three (25 Sep, 26 Sep, 27 Sep). IIA. Geophysical Activity Summary 23/2100Z to 24/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 627 km/s at 24/0257Z. Total IMF reached 6 nT at 24/0727Z. The maximum southward component of Bz reached -3 nT at 24/2045Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 593 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on days one, two, and three (25 Sep, 26 Sep, 27 Sep). III.
