Bulletin

Over the past 24 hours solar activity has been very low. The visible solar disc was spotless and no significant flares have been recorded. No Earth directed Coronal Mass Ejections (CMEs) have been detected in the available coronagraph imagery. The greater than 10MeV proton flux remained at background levels over the past 24 hours. Solar activity is expected to remain very low over the next 24 hours.

The solar wind was at background levels over the last 24 hours, gradually increasing over the period from 300 km/s to 340 km/s. The total magnetic field strength fluctuated between 0.2 and 4.9 nT. The Bz component ranged between approximately -4 and +3.5 nT.

Geomagnetic conditions have been quiet to unsettled over the past 24 hours, with Kp index (NOAA) ranging between 0-2 and local K index (Dourbes) ranging between 0-2, with one short interval of K equal to 3 at 18 UT on 25 May. Quiet geomagnetic conditions are expected over the next 24 hours. Active intervals (K Dourbes = 4) are possible on May 28, due to the expected arrival of a high speed solar wind stream associated with a recurring, negative polarity equatorial coronal hole which began to traverse the central meridian on 24 May.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 000, gebaseerd op 19 stations.
