Bulletin

In the past 24 hours, no C flares were observed. Very low solar activity (no C flares) is expected in the next 24 hours. Solar wind speed measured by DSCOVR varied between about 295 and 320 km/s in the past 24 hours, while the magnitude of the Interplanetary Magnetic Field (IMF) varied between about 1 and 5 nT. Quiet geomagnetic conditions (K Dourbes between 0 and 2; NOAA Kp between 0 and 1) were registered in the past 24 hours. Quiet to unsettled levels (K Dourbes < 4) are expected on February 15 and 16. Due to the expected arrival of a high speed stream from a positive coronal hole, quiet to active geomagnetic conditions (K Dourbes < 5) are possible on February 17, with a slight chance for minor storm levels (K Dourbes = 5).

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 023, gebaseerd op 19 stations.
