Bulletin

The solar flaring activity remained low with only two low C-class flares reported during last 24 hours. As all the active regions presently observed on the visible side of the Sun have rather simple configuration of their photospheric magnetic field, we can expect a low flaring activity to persist in the coming hours. During last 24 hours there were no potentially Earth-directed CMEs detected in the coronagraph observations.

The greater than 10 MeV proton flux remained at the background levels, and the greater than 2 MeV electron flux was under the 1000 pfu threshold. The 24h electron fluence is at normal level. We do not expect change in any these three parameters in the coming 24 hours.

Earth is still inside the slow solar wind with velocity of about 315 km/s. The interplanetary magnetic filed magnitude is also low and it amounts 3 nT. The solar wind originating from the small positive polarity coronal hole that has rotated across the central meridian on November 22, might be expected at Earth starting from tomorrow. During last 24 hours the geomagnetic conditions were quiet and we expect such a geomagnetic conditions to persist in the coming hours.

Estimation du nombre international de taches solaires (ISN) pour aujourd'hui : 068, sur la base de 17 stations.
