Bulletin

The strongest flare in the past 24 hours was an impulsive X2.2 flare peaking at about 11:42 UT on June 10. The flare originated from the active region which just rotated from the behind of the east solar limb. The SDO/AIA data indicate that the flare was possibly associated with the CME. The active region at the east solar limb which produced the X-class flare today is very likely to be the source of more strong flares. We therefore expect C-class, M-class and also possibly X-class flares. The Catania sunspot groups 69 and 76 (NOAA AR 2080 and 2085, respectively) which currently have beta-gamma-delta configuration of the photospheric magnetic field are also very probable source of flaring activity. The Catania sunspot groups 69 and 76 (NOAA AR 2080 and 2085, respectively) are currently situated in the western solar hemisphere. The major eruption from one of these sunspot groups may lead to a proton event, so we issue warning condition for a proton event. The solar wind speed is about 430 km/s, and the interplanetary magnetic field magnitude is currently 7 nT. We expect quiet geomagnetic conditions in the coming hours.

Estimation du nombre international de taches solaires (ISN) pour aujourd'hui : 115, sur la base de 16 stations.
