Bulletin

The solar activity has been at very low levels over the past 24 hours. The Sun is currently spotless and the X-ray flux remained below B-level. Solar activity is expected to remain at low levels for the next 24 hours.

No earth-directed coronal mass ejections (CMEs) have been observed in the available coronagraphic imagery. The greater than 10 MeV proton flux was at nominal values.

The solar wind was slightly enhanced over the past 24 hours: The total magnetic field fluctuated around 10 nT, the solar wind speed varied around 315 km/s, and the southern component of the magnetic filed remained positive. After this relatively short and minor disturbance, the solar wind parameters are expected to return to the nominal level within the next 24 hours.

Quiet geomagnetic conditions were observed over the past 24 hours, and is expected to remain so for the next period.

Estimation du nombre international de taches solaires (ISN) pour aujourd'hui : 000, sur la base de 13 stations.
