Solar activity was at moderate levels. The largest flare of the period was optically uncorrelated, an M1 occurred at 02/2148 UTC. Region 9767 (S23E23) produced a C5/1f at 03/0220 UTC that had an associated radio sweep with an estimated shock velocity of 410 km/s. LASCO imagery doesn't depict the presence of an associated halo with this event. Although this region has been spotless for several days, Region 9758 (N13W84),produced several Sf optical flares today. Other activity included a couple small C-class flares from regions 9770 (N09W41) and 9754 (S05W81). New Region 9772 (S18E83) was numbered today.

Solar activity is expected to be at moderate levels.

The geomagnetic field has been at quiet levels. The greater than 10 MeV proton event that began on 30/0245 UTC remains in progress, maximum flux was 108 pfu at 31/1620 UTC.

The geomagnetic field is expected to be at quiet levels on days one and two of the forecast period. Day three could see some isolated active conditions due to the ejecta indicated by the Type II radio sweep mentioned in 1A. The greater than 10 MeV proton event is expected to end on day one.
