Bulletin

The strongest flare in the past 24 hours was a C1.1 event that occurred today at 05:52 UT in NOAA AR 2130. NOAA ARs 2132 and 2134 are stable and have simplified. We expect more flaring at C-class level in the coming days. A filament eruption was observed near NOAA AR 2127 at 10:40 UT today. No coronagraph images are currently available, but due to the location near the west limb a possible associated CME is not expected to be earth-directed. Activity seems to be increasing in the active region complex formed by NOAA active regions 2127, 2128 and 2130. These regions are currently close to the west limb. In case of a strong eruption occurs there, a proton event is not excluded. Therefore we issue a warning condition. The solar wind has returned to quiet conditions. Unsettled geomagnetic conditions (K up to 3) are possible later today or tomorrow in case a coronal hole high speed wind stream should arrive.

Estimation du nombre international de taches solaires (ISN) pour aujourd'hui : 085, sur la base de 20 stations.
