Bulletin

Three active region visible on the Sun (beta magnetic field configuration). There have been no C-class flares in the past 24 hours, they are possible in the next 24 hours.

The partial halo CME from November 24 is expected to arrive early on 28 November.

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. The greater than 2 MeV electron flux was slightly over the threshold for a few hours, it may increase again over the threshold in the next 24 hours. The greater than 2 MeV electron fluence was at normal levels in the past 24 hours, and is expected to stay at normal levels or go into moderate levels in the next 24 hours.

The solar wind speed as registered by DSCOVR is around 340 km/s. The Interplanetary Magnetic Field near Earth (IMF) magnitude is about 5 nT. There were no extended intervals with Bz below -5 nT. A high speed solar wind stream can be expected today.

Quiet conditions (K-BEL and Kp between 0 and 2) were registered in the past 24 hours. Active and minor storm conditions are be possible upon the arrival of the high speed solar wind stream and the ICME from 24 November.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 037, gebaseerd op 14 stations.
