Bulletin

There are no active regions visible on the solar disk. No C-class flares in past 24 h. Solar activity is expected to remain at very low levels.

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 350 km/s with interplanetary magnetic fields of 5 nT. Geomagnetic conditions have been quiet to unsettled (K = 1 - 3) in the past 24 h. A relatively long magnetic field with low variability together with low temperature could have marked the arrival yesterday of the March 12 CME. The effect of a high speed stream from a small equatorial coronal hole, with positive magnetic field polarity, may reach the Earth in about 24 h and cause up to active geomagnetic storm conditions (K = 4).

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 013, gebaseerd op 17 stations.
