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 was around 310 km/s until 6:25 UT on February 16, when it jumped to around 370 km/s, probably marking the arrival of a high speed stream from a positive coronal hole. Since then, solar wind speed has fluctuated between 370 and 430 km/s. The magnitude of the Interplanetary Magnetic Field (IMF) was around 3 nT until about 1:45 UT on February 16, when it started rising to values around 10 nT. Quiet geomagnetic conditions (K Dourbes between 0 and 2; NOAA Kp between 1 and 2) were registered in the past 24 hours. Due to the arrival of the high speed stream, quiet to active geomagnetic levels (K Dourbes < 5) are expected on February 16, 17 and 18, with possible minor storm episodes (K Dourbes = 5).

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 014, gebaseerd op 21 stations.
