Bulletin

Solar activity is rather low. The strongest flare, among six C-class flares reported during last 24 hours was a C5.2 flare (peak time at 23:54 UT) on June 8. The flare originated from the active region just behind the east solar limb and was associated with the type II radio burst (speed of about 890 km/s) which indicates the presence of a shock wave. The associated CME was first seen in the SOHO LASCO C2 field of view at 00:00 UT on June 09, had angular width of about 70 degrees and a projected plane of the sky speed of about 1200 km/s (as reported by the CACTUS software). A partial halo CME first seen in the SOHO LASCO C2 field of view at 03:24 UT on June 08 was a back side event and will therefore not arrive at the Earth. We expect flaring activity mainly on the C-level with the possible isolated M-class flares, in particular from the Catania sunspot groups 69 and 76 (NOAA AR 2080 and 2085, respectively). The Earth is currently inside the post ICME solar wind flow with the speed of about 510 km/s. The interplanetary magnetic field magnitude is about 4 nT. The geomagnetic conditions are back to quiet level and expected to remain so in the following 48 hours.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 108, gebaseerd op 24 stations.
