Bulletin

Solar X ray flux remained below B level and with no spotted regions on the visible disk chances for any flare occurrences remain very low.

No new Earth directed CMEs have been observed in coronagraph data.

Proton flux levels were at background values and are expected to remain so.

Solar wind showed a slight enhancement with total magnetic field reaching 8nT and later on speed increasing to around 430 km/s. Solar wind conditions may increase further under the influence of the low latitude extension of the positive polarity northern polar coronal hole. Added to that there is a small possibility of minor perturbations associated to the possible passage of the ejecta of March 6 and March 7 over the next days. All those impacts are expected to be fairly minor, and are uncertain in terms of timing if identifiable at all.

Geomagnetic conditions were quiet to unsettled (local K Dourbes 0-2 and NOAA Kp 0-3). Geomagnetic conditions may experience active periods over the next days should any of the mentioned ejecta arrive at Earth and carry a distinctive southward directed magnetic field.

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