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.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 082, gebaseerd op 15 stations.
