Bulletin

Solar activity was at very low levels. The Sun has been spotless for 18 consecutive days (SILSO). No coronal mass ejections (CME) were observed over the last 24 hours. The greater than 10 MeV proton flux was at nominal values. A diffuse and fragmented negative polarity equatorial coronal hole (CH) has nearly finished its transit of the central meridian.

Solar activity is expected to remain at very low levels.

Solar wind speed undulated between 330 and 390 km/s (DSCOVR). Bz varied between -3 and +3 nT. The interplanetary magnetic field was mostly directed away from the Sun (positive sector). Quiet geomagnetic conditions were observed.

Mostly quiet geomagnetic conditions are expected until the arrival of the wind streams associated with the negative polarity CHs, currently expected for 17 June. Active geomagnetic conditions are possible from then onwards, with a chance on a minor storming episode.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 000, gebaseerd op 23 stations.
