Bulletin

Solar activity was moderate with numerous C-class flares and one M1.3 flare. Catania sunspot region 79 (NOAA active region 2360 ) was the main responsible region. In addition Catania region 87 (NOAA AR 2367) produced a few lower C-class flares. Catania regions 79 and 83 (NOAA AR 2366) retain their beta-gamma complexity, while Catania regions 79 and 87 have grown. There are a few new (yet unnumbered) sunspot regions emerging that will be monitored. No Earth-directed CME were observed.

Solar wind was slightly disturbed due to arrival of a weak transient, probably related to the June 9 CME. The magnitude of the interplanetary magnetic field (IMF) started to increase at 12:30 UT from 5 to 11 nT, peaking in the time slot 20:15-21:00 UT and then decreased again. Solar wind speed was variable with values in the range 460-540 km/s. Geomagnetic conditions were quiet to unsettled (K up to 3) at local (Dourbes) and global (NOAA planetary) levels. Geomagnetic conditions are mainly expected to be quiet, but might become enhanced upon the arrival of a coronal hole high speed stream.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 077, gebaseerd op 17 stations.
