Bulletin

Only one C-class flare took place in the past 24 hours: the C1.0 flare peaking at 19:46 UT on June 21 in the Catania sunspot group 89 (that, together with the Catania sunspot group 90, constitutes the NOAA AR 2093). It was accompanied by small coronal dimmings and a post-eruption arcade, but the associated CME (if any) was weak and narrow, so we do not expect it to arrive at the Earth. We expect flaring at the C-level in the Catania sunspot group 89 and in an unnumbered sunspot group that appeared from behind the east limb yesterday evening. The Earth is currently inside a slow (around 370 km/s) solar wind flow with average (around 5 nT) interplanetary magnetic field magnitude. The geomagnetic conditions are quiet and are expected to remain so until June 24, when we expect the arrival of the ICME associated with the partial halo CME on June 20, which may result in active to minor storm conditions.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 063, gebaseerd op 18 stations.
