Solar activity has been moderate. The largest event of the day was an M1/1b flare from Region 9368 (N26W44) at 09/0157 UTC. A long duration M1 flare also occurred at 09/1028 UTC, but without definitive optical correlation. Possible sources indicated by EIT imagery include east and west limb activity as well as Region 9370 (N11W24), but LASCO data indicate no associated CME. Newly numbered and rapidly developing Region 9372 (S37W50) produced several C-class flares, the largest a C7/Sf at 09/2027 UTC. Region 9373 (S07E71) was also numbered today.

Solar activity is expected to be low to moderate. Active regions noted in section 1A above are all possible sources of isolated M-class activity.

The geomagnetic field was quiet to unsettled. Greater-than-2 MeV electrons at geosynchronous orbit were moderately enhanced.

The geomagnetic field is expected to be at quiet to unsettled levels through day one. Isolated active and minor storm periods are possible on days two and three, primarily due to the expected influence of a recurrent coronal hole. There is also a small chance for peripheral transient effects from the CME activity of 8 March during the same period.
