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 increased from about 400 to a maximum around 680 km/s in the past 24 hours, with current values around 550 km/s. The magnitude of the Interplanetary Magnetic Field (IMF) varied between about 2 and 17 nT with current values around 4 nT. There were no long-lived negative Bz excursions. Continued high speed solar wind conditions are expected within the next 24 hours. Late on May 16 or on May 17, a glancing blow from the partial halo CME of May 13 may further enhance solar wind conditions. Quiet to unsettled geomagnetic conditions (K Dourbes between 2 and 3; NOAA Kp between 2 and 4) were registered in the past 24 hours. Under the influence of a high speed stream from a positive equatorial coronal hole, active geomagnetic levels (K Dourbes = 4) are possible on May 16, 17 and 18, with a chance for minor geomagnetic storm intervals (K Dourbes = 5) late on May 16 or on May 17.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 025, gebaseerd op 20 stations.
