Bulletin

There were no flares on the visible solar disc of the Sun in the past 24 hours. The chance for a C flare in the next 24 hours is estimated at only 2%.

No Earth-directed Coronal Mass Ejections (CMEs) were observed in available coronagraphic imagery.

The greater than 10 MeV proton flux was at nominal levels in the past 24 hours, and is expected to stay at nominal levels in the next 24 hours.

In the past 24 hours, solar wind speed near Earth as registered by DSCOVR rose from about 550 to 650 km/s and then decreased to current values around 475 km/s. The Interplanetary Magnetic Field (IMF) was predominantly directed towards the Sun and its magnitude varied between about 1 and 7 nT. Bz was never below -5 nT. Solar wind speed is expected to further decrease over the next days.

Quiet geomagnetic conditions (K Dourbes between 1 and 2; NOAA Kp between 1 and 2) were registered in the past 24 hours. Quiet to unsettled conditions (K Dourbes < 4) are expected on November 13, 14 and 15.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 011, gebaseerd op 17 stations.
