Bulletin

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

There are currently no SoHO-LASCO coronagraph observations available, STEREO-A COR coronagraph and SDO-AIA EUV observations indicate no Earth- directed CMEs (Coronal Mass Ejection) were produced. Without LASCO data to corroborate the absence of a CME, these observations should be treated with caution, with the small possibility of an unobserved Earth directed CME having been produced.

Proton levels were at background values and are expected to remain so. The solar wind speed has fluctuated between 300 and 350 km/s over the past 24 hours. The total magnetic field strength has fluctuated between 3 and 7 nT. The Bz between -6 and 5 nT. Geomagnetic conditions ranged between Kp index 1-3 (NOAA) and local K index 0-2 (Dourbes).

Solar wind conditions are expected to be enhanced over the next 24 hours due to a high speed stream (HSS) from a recurrent equatorial coronal hole. The solar wind speed may reach speeds exceeding 500 km/s.

Geomagnetic conditions are expected to become unsettled throughout the day, with some active periods due to HSS solar wind enhancements.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 000, gebaseerd op 14 stations.
