Solar flaring activity was at very low levels. No significant flares have been recorded. A small region has appeared on the NE quadrant. Solar activity is expected to remain at very low levels.

No Earth directed Coronal Mass Ejections (CMEs) were observed in the available coronagraphic imagery.

The greater than 10 MeV proton flux was at background levels in the past 24 hours, and is expected to stay at nominal levels in the next 24 hours. The greater than 2 MeV electron flux remained below the 1000 pfu alert threshold, while the 24h electron fluence was at nominal levels over the past 24 hours. Over the next 24 hours they may increase slightly.

ver the past 24 hours the solar wind speed further increased to 510 km/s. The total magnetic field strength had values between 1 and 8 nT, while its Bz component varied between -6 and 5 nT. The interplanetary magnetic field phi angle was predominantly on the negative sector (directed towards the Sun), with small variations since Aug 11 03:30UT, possibly as a result of the extension of the northern polar coronal hole. Over the next 24 hours, solar wind conditions are expected to remain at about these levels.

Geomagnetic conditions were at quiet to unsettled levels (NOAA Kp and K Dourbes 1-3) over the past 24 hours. Quiet to unsettled conditions are expected over the next 24 hours.
