Solar activity was low. The largest event of the period was a C4/Sf at 23/0630Z from developing Region 9841 (S20W33). Region 9830 (S19W49) continues to be the largest and the most active region on the visible disk, and produced several minor C-class flares. This region has been in slow decay over the past few days; however, new flux emergence was noted today and a weak delta configuration still exists. Minor C-class activity was also observed in Region 9839 (S18W20). New Regions 9844 (N22E33), and 9845 (N15E71) were numbered today.

Solar activity is expected to be low to moderate. Region 9830 is capable of producing isolated M-class flares with the slight chance of a major flare.

The geomagnetic field was mostly quiet with isolated unsettled periods early in the period.

The geomagnetic field is expected to continue at quiet to unsettled levels. The minor geomagnetic disturbance expected today following the 20 Feb CME, has not yet materialized. It is unlikely that we will see any impact from this CME.
