Solar activity has been moderate due to an M1/1n flare at 1205 UTC from Region 162 (N25W59). Region 162 continues to show flux emergence and consolidation in the western portion of the trailer spots where the group has a delta configuration. Additional frequent C-class subflares were produced by this region throughout the day. New Region 173 (S17W69) emerged on the disk today and new Region 172 (S17E44) was assigned. An erupting prominence was observed near the northeast limb beginning around 2200 UTC and was associated with a narrow CME in LASCO as well as a type II sweep with shock velocity of 1015 km/s. The event was promptly followed by a back-sided full halo CME which was first observed in LASCO at 2326 UTC.

Solar activity is expected to be moderate because of Region 162. There continues to be a slight chance for major flare activity from this region as well. The current observations of strong activity behind the east limb suggest that there is likely to be a gradual increase in background levels and activity levels over the next three days.

The geomagnetic field was unsettled to active. Solar wind signatures continue to indicate the presence of a high speed solar wind stream associated with a coronal hole. The greater than 2 MeV electron fluxes reached high levels today.

The geomagnetic field is expected to be mostly unsettled for the next three days as the currently enhanced conditions are expected to subside.
