Analysis of Solar Active Regions and Activity from 31/2100Z to 01/2100Z: Solar activity has been at low levels for the past 24 hours. The largest solar event of the period was a C3 event observed at 01/0743Z. There are currently 8 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 (02 Feb, 03 Feb, 04 Feb). IIA. Geophysical Activity Summary 31/2100Z to 01/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 461 km/s at 01/0757Z. Total IMF reached 8 nT at 01/0840Z. The maximum southward component of Bz reached -6 nT at 01/0802Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 238 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on days one and two (02 Feb, 03 Feb) and quiet to active levels on day three (04 Feb). III.
