Bulletin

Solar activity was at very low levels. The Sun remains spotless and no flares have been observed. No Earth directed coronal mass ejections (CME) were observed over the last 24 hours 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 at very low levels.

The solar wind speed varied between approximately 370 and 500 km/s (ACE). Bz varied between -4 and +4 nT. The interplanetary magnetic field was predominantly directed away from the Sun (positive sector). Quiet to unsettled geomagnetic conditions were observed, with the Kp index (NOAA) ranging between 0-2 and the local K index (Dourbes) ranging between 0-3 over the past 24 hours.

Quiet to unsettled geomagnetic conditions are expected due to the arrival of the solar wind stream associated with the negative polarity equatorial coronal hole, which began to transverse the central meridian on July 11.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 000, gebaseerd op 20 stations.
