Bulletin

Solar activity was very low, with one single C1.0 flare originating from NOAA active region 2396. No Earth-directed CMEs were observed. Flaring activity at the C-level is expected. Also an M-class flare is possible, though not likely.

The solar wind speed measured by ACE started to increase at 6:20 UT on August 6 from 400 km/s to currently about 500 km/s. The interplanetary magnetic field (IMF) magnitude is enhanced (up to 12 nT) in association with the apparent sector boundary crossing that occurred around 6UT. This indicates the arrival of the interaction region between the slow and fast solar wind flows, with the fast flow emanating from the small equatorial coronal hole. The geomagnetic conditions are currently quiet at planetary level and unsettled to active at local level (Dourbes). Geomagnetic disturbances at active (K=4) to minor storm levels (K = 5) may occur later today or early tomorrow.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 106, gebaseerd op 27 stations.
