Solar activity was low due to C-class x-ray events from Region 1415 (N08W84). Region 1416 (S17E10) continues to evolve developing a beta-gamma magnetic configuration. New Region 1417 (N18E59) rotated onto the disk as a B-type group. As asymmetric, full-halo CME was observed lifting off the NE limb, first seen in SOHO LASCO C2 imagery at 09/2117Z. The source region for this event appears to be located to the southwest of Region 1417. A second CME was observed in STEREO-A and B COR2 imagery, first seen on the Ahead spacecraft at 10/1154Z. The source of this CME appears to be a 23 degree long filament eruption, centered near S31E29. Analysis is ongoing on the geoeffective potential of these CMEs.

Solar activity is expected to be low with a slight chance for M-class activity for the next three days (11 - 13 February) due to the return of old Region 1402 (N26, L=218).

The geomagnetic field was at quiet to unsettled levels. ACE satellite solar wind velocities were steady through the period at about 450 km/s. The Bz component of the interplanetary magnetic field was mostly north at about 5 nT with brief southward excursions to -4 nT.

The geomagnetic field is expected to be mostly quiet on day one (11 February) through midday on day two (12 February). By midday on day two, and through day three (13 February), field activity is expected to increase to quiet to unsettled levels with high latitude active intervals. This increase in activity is due to a recurrent coronal high speed stream that is expected to rotate into a geoeffective position.
