Very low solar activity continued. New NOAA/SWPC Region 2771 (S18E43,
Bxo/beta) was assigned to a small, compact group of spots. The region
appeared to stall in development and remained magnetically weak with
minimal shear. Region 2770 (N23W44, Axx/alpha) continued to decay. No
Earth-directed CMEs were observed in available coronagraph imagery.
Despite the presence of two spotted regions on the visible disk, solar
activity is expected to remain very low, with only a slight chance for
C-class flares 13-15 Aug.
The greater than 2 MeV electron flux dropped to moderate levels and the
greater than 10 MeV proton flux maintained background values.
The greater than 2 MeV electron flux is expected to continue peaking at
moderate, with a slight chance for high flux 13-15 Aug; while the
greater than 10 MeV proton flux is expected to remain at background.
Solar wind parameters remained indicative of a slow regime. Total IMF
strength was primarily less than 5 nT and the Bz component underwent
only weak deviations. Density increased modestly; while solar wind
speeds were low at 300-325 km/s and the phi angle was predominantly
A slow solar wind regime is anticipated to continue 13-15 Aug due to
lack of influential features.
Quiet conditions still dominated the geomagnetic state.
Quiet conditions are expected 13-15 Aug in response to the continuing
ambient, slow solar wind regime.
