Bulletin

No C-class flares in past 24 h. All ARs have decayed into plages, the Sun is spotless. There is a region rotating into view from the east limb, but it does not seem very active from STEREO observations. The X-ray flux is expected to remain below C level.

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

Geomagnetic conditions have been quiet (k = 1-2). Solar wind speed has been slowly increasing since last night (but it is still slow, under 400 km/s), together with relatively elevated magnetic fields (reaching 14 nT, with Bz mostly positive). The Earth may only see the northern boundary of the high speed solar wind stream expected from the coronal hole in the southern solar hemisphere, producing only a mild geomagnetic impact. Active conditions can be expected in the next 48 h.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 000, gebaseerd op 15 stations.
