Bulletin

There are currently 6 sunspot groups visible on the solar disk. The only region that is actively flaring is NOAA 2065. It produced all 5 C-flares of the period, the strongest a C3.8 flare starting at 23:49UT on 25 May. The associated CME had a speed between 250-300 km/s and was not directed to Earth. The other regions are relatively small and have a simple magnetic configuration. C-class flares are expected, with a small chance on an M-class flare from NOAA 2065. Solar wind speed decreased from 430 to 350 km/s, with Bz varying between +3 and -3 nT. The geomagnetic field was mostly quiet, though locally brief periods with K=3 were recorded. A coronal hole (CH) that passed the central meridian (CM) on 23 May can still influence the geomagnetic field later today or tomorrow. Another CH that passed the CM last night may influence the geomagnetic field starting 29 May. Geomagnetic conditions are expected to be quiet, though locally a brief active episode on 26-27 and 29 May is not excluded.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 075, gebaseerd op 13 stations.
