Attività solare

Sommario delle 24 ore
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.
Previsione
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.

Particelle energetiche

Sommario delle 24 ore
The greater than 2 MeV electron flux dropped to moderate levels and the greater than 10 MeV proton flux maintained background values.
Previsione
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.

Vento Solare

Sommario delle 24 ore
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 positive.
Previsione
A slow solar wind regime is anticipated to continue 13-15 Aug due to lack of influential features.

Geospace

Sommario delle 24 ore
Quiet conditions still dominated the geomagnetic state.
Previsione
Quiet conditions are expected 13-15 Aug in response to the continuing ambient, slow solar wind regime.
