Bulletin

The solar activity has been at very low levels over the past 24 hours. The Sun is currently spotless and the X-ray flux remains below B-level. Solar activity is expected to remain at low levels for the next 24 hours.

No earth-directed coronal mass ejections (CMEs) have been observed in the available coronagraphic imagery. The greater than 10 MeV proton flux was at nominal values. The solar wind speed has decreased from around 460 to 360 km/s over the past 24 hours. The total magnetic field strength has fluctuated between 2 nT and 4 nT. The Bz component fluctuated around 0 nT, ranging between -4 and +4 nT. Geomagnetic conditions ranged between Kp index 0-3 (NOAA) and local K index 0-2 (Dourbes) over the past 24 hours.

Geomagnetic conditions are expected to remain at quiet conditions for today and tomorrow, before possibly enhancing on experiencing the 20th/21st of November, due to the arrival of a high speed stream from a small low latitude positive polarity Coronal Hole.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 000, gebaseerd op 16 stations.
