Analysis of Solar Active Regions and Activity from 24/2100Z to 25/2100Z: Solar activity has been at very low levels for the past 24 hours. There are currently 1 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be very low on days one, two, and three (26 Jan, 27 Jan, 28 Jan). IIA. Geophysical Activity Summary 24/2100Z to 25/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 332 km/s at 25/0407Z. Total IMF reached 6 nT at 25/0423Z. The maximum southward component of Bz reached -4 nT at 25/0308Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 176 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on days one, two, and three (26 Jan, 27 Jan, 28 Jan). III.
