Bulletin

Solar activity has been eruptive during the past 24 hours, featuring two low C flares from NOAA AR 11775 and 11776. More C flares are possible within the next 48 hours, with a slight chance for an M flare. The influence of the coronal hole high speed stream on the solar wind is gradually weakening. During the past 24 hours, solar wind speeds have decreased from about 520 to 440 km/s, while the IMF went further down from 4 to 2 nT. The solar wind speed is expected to continue its descent until June 28, when we will likely see the effects of another coronal hole high speed stream. Geomagnetic activity was at quiet levels (K Dourbes between 1 and 3; NOAA Kp between 1 and 2) during the past 24 hours. Quiet conditions (K Dourbes < 4) are expected for June 26 till the first half of June 28. On the second half of June 28, active periods (K Dourbes=4) are possible as a consequence of the expected arrival at Earth of a new coronal hole high spead stream.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 041, basierend auf 11 Stationen.
