Bulletin

Solar activity is low, with the last C-class flare reported on September 11 (C1.3 flare peaked at 21:37 UT). C-class flares, and possibly but not very probably also an isolated M-class flare can be expected from the NOAA AR 12415 and NOAA AR 12414 which maintained the beta-gamma configuration of its photospheric magnetic field. No Earth directed CMEs were observed in the last 24 hours.

The solar wind speed is about 480 km/s and the interplanetary magnetic field magnitude is currently 6 nT. Since 06 UT this morning the Bz component of the interplanetary magnetic field had two long southward intervals with the value of -4 nT. Currently the geomagnetic conditions are quiet. We expect such conditions to persist in the coming hours. The active to geomagnetic storm conditions are expected on September 14 due to arrival of the fast flow from the low latitude coronal hole at north solar hemisphere which has crossed central meridian on the mid-day of September 11.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 083, basierend auf 09 Stationen.
