Bulletin

NOAA AR 2651 has decayed into a beta region and produced no C-class flares in past 24 h, but they remain likely to occur in the coming hours.

No Earth directed Coronal Mass Ejections (CMEs) have been detected (although coronagraph data is unavailable at the moment of writing). Solar protons have remained at background levels over the past 24 hours.

The expected high speed stream has arrived to the Earth with solar wind speeds reaching 585 km/s (but still increasing) and generating active conditions locally (k=4) and moderate storms at planetary level (Kp=6) starting at midnight. The disturbed conditions are expected to continue in the coming 48 h.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 029, gebaseerd op 21 stations.
