Analysis of Solar Active Regions and Activity from 28/2100Z to 29/2100Z: 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 29/0818Z from Region 2488 (N04W66). There are currently 3 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 (30 Jan, 31 Jan, 01 Feb). IIA. Geophysical Activity Summary 28/2100Z to 29/2100Z: 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 458 km/s at 28/2226Z. Total IMF reached 6 nT at 29/0151Z. The maximum southward component of Bz reached -3 nT at 29/1600Z. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on days one, two, and three (30 Jan, 31 Jan, 01 Feb). III.
