Bulletin

One M-class and six C-class flares were observed during the past 24 hours. Catania sunspot group 69 (NOAA AR 2080) was the main source region. The M1.4 flare peaked at 19:31 on 6 June. Catania group 69 is currently magnetically most complex and has also developed a delta component. Catania groups 71 and 76 (resp NOAA ARs 2082 and 2085) have developed to beta-gamma regions. An asymmetric halo CME was observed in coronagraphic imagery (SOHO/LASCO C2,C3, STEREO A & B COR2). It was first visible in SOHO/LASCO C2 from 13:25 UT on 6 June and is mainly propagating east of the Sun Earth line. Associated activity is observed by STEREO A & B EUVI 195 near old region NOAA 2065 at the far side of the Sun. The event is thus backsided and will not be geoeffective. More M-class flare are expected during the next 48 hours, with Catania group 69 as main source candidate, but also Catania groups 71 and 76 could produce flares. Stable solar wind conditions continue with a solar wind speed between 320 and 400 km/s and the magnitude of the IMF maximally reached 6 nT. The Bz-component was fluctuating from -5 to +4 nT. Quiet geomagnetic conditions were observed and are expected to continue. There is still some chance for enhanced to active conditions for the next 24 hours as a consequence of the potential arrival of a coronal hole high speed stream.
