NOAA 2585 retained its small delta structure and produced several B-class events, the strongest a B8.2 flare peaking at 19:17UT. NOAA 2588 produced a B7.9 flare peaking at 03:23UT. About an hour later, this event was followed by the disappearance of the southern portion of a small filament just 10 degrees southeast of this active region. Only mild coronal dimming was observed in AIA193, and no type II radio-burst was reported. The 40-degrees long filament in the northwest quadrant remained quiet. Currently available coronagraphic imagery revealed no earth-directed coronal mass ejections (CME).

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

Solar wind speed was near nominal values, decreasing further from 460 to 410 km/s. Bz fluctuated between -4 and +5 nT, being mostly positive. The interplanetary magnetic field (IMF) was predominantly directed away from the Sun (positive). Geomagnetic activity evolved from mostly unsettled to quiet.

Mostly quiet to unsettled geomagnetic conditions are expected. There's a small chance that a high speed stream from polar coronal hole extensions, in particular from one at +30 degrees, may influence the earth environment from 11 September onwards, increasing the likelihood on an active geomagnetic episode.
