Bulletin

The recurrent regions rotating over the east limb produced a C3.3 flare, peaking at 09:41 UT. Dimmings indicate that a CME may have been associated with this flare, but no coronagraph data is available yet to confirm. More C-class flares are expected, and M-class flares are possible.

No Earth directed Coronal Mass Ejections (CMEs) have been detected. Solar protons have remained at background levels over the past 24 hours.

Geomagnetic conditions have been at k = 1-2 levels. Solar wind speed is now at 325 km/s with interplanetary magnetic fields of 5 nT. A high speed solar wind from an equatorial coronal hole is expected within 24 h. Active to minor storm conditions expected.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 023, gebaseerd op 21 stations.
