Bulletin

Solar activity was very low with X-ray flux remaining below B level. Catania sunspot group 86 (NOAA active region 2713) almost fully decayed. Chances for C class flaring remain very low.

No Earth directed CMEs were observed in coronagraph images.

Solar proton flux levels were at background values and are expected to remain so.

Solar wind conditions have been nominal with solar wind speed around 300 km/s and total magnetic field below 5 nT. The Bz component of the magnetic field was variable. The magnetic field phi angle indicates a negative sector connection. Solar wind conditions are expected to remain nominal in the next 24 hours with afterwards an expected sector change and a moderate increase in solar wind speed associated to the positive polarity coronal hole in the northern hemisphere that has passed the central meridian June 14-15.

Geomagnetic conditions were quiet to unsettled (local K Dourbes 0-3 and NOAA Kp 0-1) and are expected to first be quiet and later quiet to unsettled as solar wind speed becomes slightly increased.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 014, gebaseerd op 11 stations.
