Analysis of Solar Active Regions and Activity from 29/2100Z to 30/2100Z: Solar activity has been at very low levels for the past 24 hours. There are currently 4 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be at very low to low levels on days one, two, and three (31 Jan, 01 Feb, 02 Feb). IIA. Geophysical Activity Summary 29/2100Z to 30/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed, as measured by the ACE spacecraft, reached a peak speed of 372 km/s at 30/0002Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 171 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels for the next three days (31 Jan, 01 Feb, 02 Feb). III.
