Bulletin

Flaring activity was low with one C5.8 flare erupting from Catania sunspot region 79 (NOAA active region 2360). More C-class flares are expected, with a slight chance for an isolated flare at the M-level. No Earth-directed CMEs were observed.

Solar wind is still under influence of the coronal hole high speed stream. The solar wind speed has reached values above 700 km/s and currently remains around 600 km/s. The total magnetic field has values between 4 and 8 nT, with a fluctuating Bz component. At local (Dourbes) and global (NOAA estimated Kp) level, active to minor storm conditions (K= 4 and 5) were reached in the second half of the UT day on June 8. Geomagnetic conditions are currently quiet to unsettled (K=1 to 3). Mostly quiet to unsettled conditions are expected. Subject to the Bz orientation, there is some chance for a few time slots of active conditions during the next 24 hours.

Estimation du nombre international de taches solaires (ISN) pour aujourd'hui : 076, sur la base de 13 stations.
