Solar flaring activity was at moderate levels over the past 24 hours, with numerous C-class flares originating from NOAA ARs 3088 and 3089. NOAA AR 3089 was additionally the place of origin of 4 M-class flares, with M7.2-class flare, peak time 26 August 12:14 UTC, the one with the largest X-ray output. NOAA ARs 3088 and 3089 have both grown over the past 24 hours, while NOAA AR 3085 was rather stable. For the next 24 hours, M-class flares are expected while X-class flares are possible.

A filament eruption was observed around NOAA AR 3088 at 26 August 06:38 UTC. This followed the C7.0-class flare, peak time 06:28 UTC from the same area. It is not clear whether a signature in Lasco C2 at 07:24 UTC is from an associated Coronal Mass Ejection. More will be reported as more data become available.

The greater than 10 MeV proton flux was at nominal levels in the past 24 hours. The proton flux could be elevated the next 24 hours in case of strong flaring activity, else it can be epxected to be at nominal levels. The greater than 2MeV electron flux was about the 1000 pfu threshold over the past 24 hours. It is expected to be about threshold over the next 24 hours. The 24h electron fluence was at moderate levels over the past 24 hours. It is expected to be at moderate levels over the next 24 hours.

The solar wind parameters had values at background levels over the past 24 hours. The solar wind magnetic field values fluctuated between 4 and 7 nT, while Bz had values between -4 and 5 nT. The solar wind speed averaged around 350 km/s. The interplanetary magnetic field phi angle was predominantly on the negative sector (towards the Sun). Over the next 24 hours, we are expecting this general trend to continue.

Quiet conditions were recorded over the past 24 hours (NOAA Kp and K Dourbes 0-2). Over next the 24 hours, quiet to unsettled conditions are expected.
