Bulletin

Solar X-ray flux remained below B level throughout the period. There are no active regions on disk and chances for flaring at C level are very low.

No Earth directed Coronal Mass Ejections (CME's) have been observed in coronagraph data.

The greater than 10 MeV proton flux was at nominal levels in the past 24 hours, and is expected to remain so in the next 24 hours. The greater than 2 MeV electron flux is above 10^4 pfu, continuously exceeding the 10^3 pfu threshold in the past 24 hours. The electron flux is expected to remain elevated over the next days.

Solar wind is in a near nominal regime. Solar wind speed decreased from around 400 km/s at the start of the period to a minimum of 317 km/s and is now around 350 km/s. The total magnetic field was mainly below 5 nT, but currently reaches close to 6nT. The Bz component has been variable with values reaching -5nT, this morning. The magnetic field phi angle indicated connection with the positive sector (magnetic field oriented away from the Sun), though was somewhat more variable this morning. Near nominal Solar wind conditions are expected over the next days.

Geomagnetic conditions were quiet (NOAA Kp 0-1 and local K Dourbes 0-2). Quiet geomagnetic conditions are expected for the next days.

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