Solar activity was at moderate levels. Region 9767 (S18W87) produced an M1/Sf flare at 11/0807 UTC. This region has shown signs of slight decay as it approached the west limb. Region 9773 (N15W32) produced four minor C-class flare and remains a magnetically complex beta-gamma-delta region. There has been growth in the area coverage of this region but reduced spot count. Two new regions were numbered today: Region 9781 (S06E64) and Region 9782 (N08E73). Region 9782 is believed to be the return of old Region 9742 which was quite active while on the disc.

Solar activity is expected to be moderate with Regions 9773 (N14W32) and 9778 (S16E33) the most promising flare sites.

The geomagnetic field was at unsettled to active levels, due to a high speed solar wind stream. The greater than 10 MeV proton event that began at 10/2045 utc, reached a tentative maximum of 91 pfu at 11/0530 UTC. The flux is slowly declining.

The geomagnetic field is expected to persist at unsettled to active levels for the next 48 hours. Strictly unsettled conditions should end the period. The satellite proton event is expected to continue for at least another 24 hours.
