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 ranged between 380 and 430 km/s (DSCOVR) over the past 24 hours. The total magnetic field was at or below 5 nT. Bz ranged between -4 and +4 nT. The direction of the interplanetary magnetic field (phi angle) was mostly directed away from the Sun (positive sector). For the next 24 hours the solar wind speed is expected to remain at nominal levels.

Geomagnetic activity was mostly quiet (local K Dourbes and NOAA Kp recorded values between 0-3 and 1-2, respectively). Geomagnetic conditions are expected to be mostly quiet on 17 - 19 July.

Estimation du nombre international de taches solaires (ISN) pour aujourd'hui : 000, sur la base de 18 stations.
