Bulletin

The Sun activity is very quiet: The solar disc remains spotless; no flares have been observed in past 24 h and no active regions visible on the disc. The X-ray flux is expected to remain below C level.

No Earth directed Coronal Mass Ejections (CMEs) have been observed and the solar protons flux remained at background levels over the past 24 hours.

Solar wind speed has continued its slow overall decline from around 350 km/s to 300 km/s. The interplanetary magnetic field magnitude remained around 4 nT and the Bz component fluctuated between -2 and 4 nT being mainly positive. The solar wind is expected to remain at its nominal conditions until a renewed increase of solar wind conditions under the influence of a high speed stream associated with the extension of the northern polar coronal hole that has transited the central meridian on Nov 04.

Geomagnetic conditions were quiet (local K Dourbes 0-2, NOAA Kp 0-1) and are expected to remain quiet until the high speed stream reaches Earth by Nov 07 onwards.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 000, gebaseerd op 24 stations.
