Report of Solar Geophysical Activity (RSGA)IA. Analysis of Solar Active Regions and Activity from 05/2100Z to 06/2100Z: Solar activity has been at low levels for the past 24 hours. The largest solar event of the period was a C7 event observed at 06/0431Z from Region 1968 (N08W48). There are currently 7 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 (07 Feb, 08 Feb, 09 Feb). IIA. Geophysical Activity Summary 05/2100Z to 06/2100Z: The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed, as measured by the ACE spacecraft, reached a peak speed of 465 km/s at 06/0512Z. Total IMF reached 9 nT at 06/0218Z. The maximum southward component of Bz reached -6 nT at 06/0831Z. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on day one (07 Feb), quiet to minor storm levels on day two (08 Feb) and quiet to active levels on day three (09 Feb). Protons have a slight chance of crossing threshold on days one, two, and three (07 Feb, 08 Feb, 09 Feb). III.
