Bulletin

NOAA AR 2733 produced a C1.9 flare, at 10:34 UT. Solar activity is expected to remain at low levels with more C-class flares possible from NOAA AR 2733 (beta magnetic field configuration) as it rotates over the west limb.

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

The solar wind speed is at 360 km/s with interplanetary magnetic fields of 3 nT. Geomagnetic conditions have been quiet. The fast solar wind associated with a negative polarity equatorial coronal hole is expected to arrive to the Earth within 48 hours, causing disturbed conditions (with k values possibly reaching up to 5). Quiet conditions are expected until then.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 014, gebaseerd op 19 stations.
