Bulletin

Solar activity was at very low levels on a spotless solar disk. No significant flares were detected in the last 24 hours and none are expected in the next 24 hours. No Earth-directed coronal mass ejections (CMEs) were detected in the available coronagraph imagery.

The greater than 10 MeV proton flux was at nominal levels in the past 24 hours and is expected to remain so in the next 24 hours. The greater than 2MeV electron flux remained under the 1000 pfu threshold and is expected to remain so. The 24h electron fluence was at nominal levels and is expected to remain so.

Over the past 24 hours the solar wind parameters based on ACE and DSCOVR were at rather low levels. The total magnetic field and its Bz component varied weakly within 2.6 nT to 5 nT and -3 nT to 3 nT, respectively. The phi angle remained in the positive sector. The solar wind speed was slow in the range of 360 km/s to 416 km/s.

Quiet geomagnetic conditions were observed over the past 24 hours and quiet conditions are expected in the next 48 hours.

Estimation du nombre international de taches solaires (ISN) pour aujourd'hui : 000, sur la base de 08 stations.
