Bulletin

There are no active regions visible on the disk. Solar activity has been very low over the past 24 hours, no significant flares have been recorded. No Earth directed CMEs have been observed in past 24 hours. A small eruption was observed on the east limb of the Sun at 18:30 UT on September 11, but it is not expected to affect Earth. The greater than 10MeV proton flux remained at background levels over the past 24 hours.

Solar activity is expected to remain low.

The solar wind speed gradually decreased over the last 24 hours, recording values between 380 and 450 km/s. The interplanetary magnetic field was predominantly directed away from the Sun (positive sector) and fluctuated between 1 and 5 nT. The Bz fluctuated between -4 and +4 nT. Geomagnetic conditions have been quiet to unsettled over the past 24 hours, with the Kp index (NOAA) and the local k index (Dourbes) recording values between 1-3 and 0-3, respectively.

Quiet conditions are expected to continue over the next 48 hours, with isolated unsettled intervals possible.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 000, gebaseerd op 25 stations.
