Solar activity was at low levels. The largest event was a C5/1f at 12/0837 UTC from Region 9866 (S10E35). Region 9866 is the most active region and continues its gradual growth with a beta-gamma-delta magnetic configuration in the larger trailing spot. A long duration C3.0 peaked at 12/0109 UTC with an overall duration of 5 hours 16 minutes. A full halo CME and Type IV radio sweep were associated with this event. The source of the CME is unclear. Activity in Region 9866 at that time suggest a possible source as does activity beyond the southeast limb.

Solar activity is expected to be low to moderate. Region 9866 continues to grow and has the potential for major flare activity.

The geomagnetic field was quiet to unsettled.

The geomagnetic fields is expected to be quiet to unsettled on day one and two of the forecast period. On day three, there is a chance of active conditions due to the CME early on 12 March.
