Solar activity

24 h Summary
Solar activity was at very low levels. No Earth-directed CMEs were observed in available coronagraph imagery.
Forecast
Solar activity is expected to continue at very low levels on 26-28 Aug.

Energetic Particles

24 h Summary
The greater than 2 MeV electron flux reached moderate levels. The greater than 10 MeV proton flux remained at background levels.
Forecast
The greater than 2 MeV electron flux is expected to be at normal to moderate levels on 26-28 Aug. The greater than 10 MeV proton flux is expected to remain at background levels.

Solar Wind

24 h Summary
Solar wind parameters, as measured by the ACE satellite, reflected nominal conditions. Total magnetic field strength remained below 5 nT and solar wind speeds were steady between 310-330 km/s. Phi angle was variable.
Forecast
Solar wind parameters are expected to become enhanced late on 26 Aug in response to the onset of a negative polarity CH HSS. Solar wind speed enhancements are expected to continue through 27 Aug and wane over 28 Aug.

Geospace

24 h Summary
The geomagnetic field was quiet.
Forecast
The geomagnetic field is expected to reach unsettled to active conditions late on 26 Aug in response to the onset of influence from a CH HSS. Active conditions are expected to continue through 28 Aug and decrease to unsettled levels on 29 Aug as influence from the CH HSS wanes.
