Analysis of Solar Active Regions and Activity from 28/2100Z to 29/2100Z: Solar activity has been at moderate levels for the past 24 hours. The largest solar event of the period was an M2 event observed at 28/2216Z from Region 1967 (S12E67). There are currently 5 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is likely to be moderate with a slight chance for an X-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 530 km/s at 29/0903Z. Total IMF reached 12 nT at 28/2225Z. The maximum southward component of Bz reached -6 nT at 29/0708Z. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on day one (30 Jan), quiet to unsettled levels on day two (31 Jan) and quiet levels on day three (01 Feb).
