Solar activity increased to moderate levels. Region 9791 (S02W46) produced an impulsive M1/1n flare at 22/0900 UTC. The sunspot group appears to have simplified somewhat since the flare occurred, reducing penumbral coverage to about half of what was observed yesterday. Region 9789 (N18W42) produced an impulsive C5/Sf flare at 22/1313 UTC and has also been in decay since flare occurrence. One event of note, an optically uncorrelated near long duration C1 flare occurred at 22/0758 UTC. This flare had an associated Type II radio sweep with an estimated shock velocity of 1017 km/s. LASCO imagery doesn't indicate earth directed CME activity with any of today's events. Regions 9787 (S06E19) and 9788 (N18E00) have shown growth over the period as both regions have acquired gamma classification to their magnetic structures. No new regions were numbered today.

Solar activity is expected to be at low to moderate levels. Regions 9787 and 9788 have the potential of producing M-class flare activity.

The geomagnetic field activity was at quiet to unsettled levels.
