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 C8 event observed at 07/0618Z from Region 3599 (S12W02). There are currently 7 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 450 km/s at 07/2043Z. Total IMF reached 8 nT at 07/1828Z. The maximum southward component of Bz reached -7 nT at 07/1814Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 177 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on day one (08 Mar), quiet to minor storm levels on day two (09 Mar) and quiet to unsettled levels on day three (10 Mar).
