Solar activity was low. Regions 1519 (S15W18), 1520 (S17E06) and 1521 (S22W07) all produced C-class flares during the period. The largest event was a C9/1n at 11/0831Z from Region 1521. Region 1520 indicated consolidation and rotation in its trailer spots while developing additional sheer. The region remained a complex beta-gamma-delta magnetic configuration. During the past 24 hours, Region 1521 elongated along its E/W axis and developed a gamma configuration in its trailer spots. The region is now classified as an E-type beta-gamma group. A 20 degree long filament erupted in the NE quadrant of the disk at about 11/0930Z. The eruption occurred along a channel centered near N22E22. Limited LASCO imagery hinted at a possible CME that lifted off the NNE limb likely associated with the filament eruption. Further analysis of this CME is ongoing.

Solar activity is expected to be moderate with a slight chance for X-class events for the next three days (12 - 14 July).

The geomagnetic field was at predominately quiet to unsettled levels with isolated high latitude minor to major storm intervals from 11/0600 - 1200Z. ACE solar data indicated wind velocities remained steady at about 500 km/s while the Bz component of the interplanetary magnetic field did not vary much beyond +/- 5 nT. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels during the period.

The geomagnetic field is expected to be at mostly quiet to unsettled levels for the next three days (12 - 14 July).
