Bulletin

Solar X-ray flux remained below B class levels throughout the period. The Solar disk is spotless and the X-ray flux is expected to remain at or below background levels.

There were no Earth-directed Coronal Mass Ejections (CME) observed in coronagraph data.

Proton levels were at background values and are expected to remain so.

The solar wind speed has increased from 500 to 700 km/s yesterday as we entered a high speed stream (HSS) from a recurrent positive polarity coronal hole, and has remained at high levels since then. The total magnetic field strength has fluctuated between 6 and 15 nT. The Bz ranged between -10 and 6 nT. Geomagnetic conditions ranged between Kp index 1-5 (NOAA) and local K index 2-5 (Dourbes).

The Solar wind conditions will remain at enhanced levels over the next 24 hours before slowly declining over the following days.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 000, gebaseerd op 19 stations.
