Bulletin

During the past 24 hours, only three C-class flares were reported, and all of them were weak (below C2 level). NOAA AR 2089 has the beta-gamma configuration of its photospheric magnetic field, but it produced only one C-class flare during this period. We expect flaring activity to continue on the C-level, in particular in NOAA ARs 2087 and 2089, as well as in the newly emerged NOAA AR 2095. Yesterday evening the interplanetary magnetic field (IMF) magnitude reached 10 nT, with intervals of negative north-south IMF component. Active to minor storm geomagnetic conditions were reported (Kp = 5 by NOAA, K = 5 by IZMIRAN, K = 4 by Dourbes). Currently the Earth is inside a slow (around 440 km/s) solar wind flow with average (around 5 nT) IMF magnitude. The geomagnetic conditions are quiet and are expected to remain so.

Estimation du nombre international de taches solaires (ISN) pour aujourd'hui : 068, sur la base de 13 stations.
