Activitat solar

Resum de 24 h

Solar activity has been at low levels with mostly weak C-class flares observed from Regions 4172 (N09W74, Dao/beta-gamma) and 4180 (S02E16, Dao/beta). There are 12 regions on the disk with most being simple in magnetic complexity. Region 4172 remained the largest region on the disk and continued to decay with its magnetic field decreasing in complexity. All remaining regions were quiet and stable. No Earth-directed CMEs were observed in available coronagraph imagery.

Previsió

Solar activity is likely to continue at low to moderate levels through 18 August.

Partícules energètiques

Resum de 24 h

The greater than 2 MeV electron flux was at moderate to high levels. The greater than 10 MeV proton flux remained at background level.

Previsió

The greater than 2 MeV electron flux is expected to be at moderate to high levels through 18 Aug. The greater than 10 MeV proton flux is expected to remain at background levels through 18 Aug.

Vent solar

Resum de 24 h

Solar wind parameters reflected nominal conditions.

Previsió

Nominal conditions are expected through 17 August. Enhanced solar wind parameters are likely on 18 Aug due to the arrival of a CIR ahead of a recurrent, negative polarity CH HSS.

Geoespai

Resum de 24 h

The geomagnetic field has been at quiet to unsettled levels.

Previsió

As CH HSS influences wane, mostly quiet to unsettled conditions are expected to persist through 17 Aug. Unsettled to active levels are likely on 18 Aug due to the aforementioned CIR and subsequent negative CH HSS.
