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 decreased from about 400 to 370 km/s until around 20h UT on May 18, when it increased again to current values of about 480 km/s. The magnitude of the Interplanetary Magnetic Field (IMF) varied between about 3 and 13 nT. Quiet to unsettled geomagnetic conditions (K Dourbes between 1 and 3; NOAA Kp between 1 and 3) were registered in the past 24 hours. Active (K Dourbes = 4) to minor storm conditions (K Dourbes = 5) are possible on May 19, 20 and 21, due to the expected high speed stream from a negative equatorial coronal hole.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 023, gebaseerd op 15 stations.
