Analysis of Solar Active Regions and Activity from 06/2100Z to 07/2100Z: Solar activity has been at low levels for the past 24 hours. The largest solar event of the period was a C1 event observed at 07/1504Z from Region 2961 (S13W55). There are currently 5 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 (08 Mar, 09 Mar, 10 Mar). IIA. Geophysical Activity Summary 06/2100Z to 07/2100Z: The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed reached a peak of 538 km/s at 06/2322Z. Total IMF reached 5 nT at 07/1515Z. The maximum southward component of Bz reached -4 nT at 07/1706Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 10194 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on day one (08 Mar), quiet levels on day two (09 Mar) and quiet to active levels on day three (10 Mar).
