Bulletin

Solar X ray flux remained below B level throughout the period. The region in the northern hemisphere, responsible for the M1 flare a few days ago, had decayed to plage and remained quiescent, although it remains to be watched. Overall probability for flaring is low.

There were no Earth directed Coronal Mass Ejections (CMEs) observed in coronagraph data.

The greater than 10 MeV proton flux levels were at background values and are expected to continue to be at background level. The greater than 2 MeV electron flux has been nominal over the past days.

Solar wind was in a near nominal regime. Solar wind speed was around 400 km/s and total magnetic field around 4nT with the magnetic field phi angle stable in the negative sector. We are expecting near nominal conditions to continue over the next 48 hours.

Geomagnetic conditions were quiet (both NOAA Kp and local K Dourbes 0-2) and geomagnetic conditions are expected to remain quiet over the next 48 hours.

Estimation du nombre international de taches solaires (ISN) pour aujourd'hui : 006, sur la base de 30 stations.
