Bulletin

Solar activity was at very low levels and is expected to remain so.

No earth-directed coronal mass ejections (CMEs) were observed in the available coronagraphic imagery.

The greater than 10 MeV proton flux and the greater than 2 MeV electron flux were at nominal levels during the last 24 hours and are expected to remain so for the next 24 hours.

The solar wind speed showed an increasing trend with values between 360 and 450 km/s (DSCOVR and ACE) over the past 24 hours. The total magnetic field was at 9 nT at the start of the period before reducing to fluctuate around 5 nT. Bz was predominantly positive, with values ranging between -6 and +4 nT. The direction of the interplanetary magnetic field (phi angle) was mostly directed away from the Sun (positive sector).

Geomagnetic activity was mostly quiet (local K Dourbes and NOAA Kp recorded values between 0-3 and 0-2, respectively). Geomagnetic conditions are expected to be mostly quiet on 16 - 19 July.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 000, gebaseerd op 11 stations.
