Solar flaring activity once more was very low. A few narrow CMEs were observed in coronagraphic data. The most interesting one being a CME travelling Northwards, related to a filament eruption, with first measurement at 14:24 UT in LASCO-C2. None of the CMEs is Earth-directed. The chances for flares at the C-level are increasing (40%). Even an M-class flare from NOAA active regions 2394 or 2396 is possible, though is not likely.

Geomagnetic conditions were quiet to unsettled (K=0 to 3) at global (NOAA estimated Kp) and local level (Dourbes), with solar wind speeds around 400 km/s and interplanetary magnetic field magnitudes near 5 nT. A similar situation is expected for the next 24 hours. The arrival of a high speed stream from a small recurrent equatorial coronal hole might result in disturbed geomagnetic levels up to active (K=4) or even minor storm levels (K=5) on August 7.
