IA. 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 C2 event observed at 07/1857Z from Region 1995 (S16W76). There are currently 9 numbered sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be low with a chance for M-class flares 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 levels for the past 24 hours. Solar wind speed at ACE reached 508 km/s at 06/2248Z. Electrons greater than 2 MeV at geosynchronous orbit reached 121 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to active levels on day one (08 Mar) and quiet to unsettled levels on days two and three (09 Mar, 10 Mar).
