Bulletin

NOAA 2585 still has a small magnetic delta and produced the strongest event of the period, a B5.3 flare peaking at 08:23UT. Gradually developing active region NOAA 2589 shows some magnetic mixing, and produced a B3 flare. No earth-directed coronal mass ejections (CME) have been observed.

A C-class flare is possible, with a small chance on an isolated M-class event.

Solar wind parameters were at nominal values, with wind speed steady near 410 km/s and Bz fluctuating between -4 and +4 nT. The interplanetary magnetic field (IMF) was mostly directed away from the Sun (positive). Geomagnetic activity was at quiet levels.

Mostly quiet geomagnetic conditions are expected. There's a small chance that a high speed stream from a polar coronal hole extension may influence the earth environment from 11 September onwards, increasing the likelihood on an active geomagnetic episode.

Estimation du nombre international de taches solaires (ISN) pour aujourd'hui : 082, sur la base de 15 stations.
