Bulletin

No active regions visible on the disk. Solar activity has been very low, no flares in the past 24 h. The situation is not expected to change in the next 48 h.

No Earth directed CMEs in past 24 h. Solar protons have remained at background levels over the past 24 hours.

The solar wind speed is at 450 km/s with interplanetary magnetic field magnitude of 4 nT. Geomagnetic conditions have been quiet. The fast solar wind stream associated with a negative polarity coronal hole is expected to arrive to the Earth within 24 h. In the previous rotation, the high speed stream originating from this coronal hole did not have any geomagnetic impact, but the coronal hole has developed and increased in size since then. Unsettled to active geomagnetic conditions can be expected.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 000, gebaseerd op 21 stations.
