Bulletin

Solar activity has been eruptive during the past 24 hours, featuring two low C flares from NOAA AR 11774 and 11778. More C flares are possible within the next 48 hours, with a slight chance for an M flare. During the past 24 hours, the solar wind speed has decreased from about about 440 to 370 km/s, while the IMF varied between 1.5 and 4 nT. Geomagnetic activity was at quiet levels (K Dourbes between 1 and 3; NOAA Kp = 1) during the past 24 hours. Quiet conditions (K Dourbes < 4) are expected for June 27. On June 28, active levels (K Dourbes=4) with minor storm periods (K Dourbes = 5) are possible as a consequence of the expected arrival at Earth of a new coronal hole high speed stream. The coronal hole high speed stream's geomagnetic effects will likely decrease on June 29, when quiet to active levels (K Dourbes < 5) are expected.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 040, gebaseerd op 12 stations.
