Solar activity was moderate due to a single M-class event during the period. Region 9601 (N14E32) produced an M1/Sn event with an accompanying 270 sfu Tenflare and a Type II radio sweep (velocity est. 961 km/s). LASCO imagery does not show any signs of an earth-directed coronal mass ejection from this event. Region 9601 has continued to show growth over the period and is capable of producing a major flare at any time. Region 9591 (S20W39) has shown some signs of minor decay during the period. It continues to retain a beta-gamma-delta magnetic configuration and is still capable of producing an isolated major flare before it rotates over the western limb on September 04-05. There are only three other spotted regions on the disk at this time. None of which have produced any significant activity.

Solar activity is expected to be moderate to high. Region 9591 and 9601 are expected to continue to produce isolated M-class events and both are capable of producing a major flare during the forecast period.

The geomagnetic field was mostly quiet to unsettled with isolated active periods.

The geomagnetic field is expected to be quiet to active with recurrent coronal hole effects beginning on 01 September. Barring any earth-directed coronal mass ejections, conditions should return to mostly quiet to unsettled on 03 September.
