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 decreased from 650 and 540 km/s over the past 24 hours. The total magnetic field strength has fluctuated around 5 nT. The Bz ranged between -4 and 4 nT. Geomagnetic conditions ranged between Kp index 2-5 (NOAA) and local K index 1-4 (Dourbes).

The enhanced solar wind conditions experienced are from a high speed stream (HSS) from a recurrent positive polarity coronal hole. The solar wind speeds are now starting to abate and should return to nominal levels in a couple of days.

Geomagnetic conditions are expected to be unsettled, with some active periods due to HSS solar wind enhancements.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 000, gebaseerd op 11 stations.
