Bulletin

NOAA 2585 is decaying and produced the only flare of the period (B3.0 peaking at 21:46UT). The other two sunspot regions (Catania 23 and 24) are small and inactive. The 40-degrees long filament in the northwest quadrant remained quiet. The coronal mass ejection (CME) associated with the prominence eruption early on 06 September (07:30-09:00UT; southwest limb) was not directed to Earth.

C-class flares are possible, with a small chance on an isolated M-class event.

Solar wind speed continued its gradual decline from about 580 km/s to its current value around 520 km/s. Bz fluctuated between -6 and +4 nT, with a sustained negative period near -5 nT from 15-19UT. The interplanetary magnetic field (IMF) was directed away from the Sun (positive). Mostly quiet to unsettled geomagnetic conditions were reported, with an isolated minor storming episode during the 18-21UT interval.

Quiet to active geomagnetic conditions are expected, with still a small chance on a minor storming episode. Geomagnetic conditions are expected to return to mostly quiet levels over the next few days in view of the gradually waning effects of the coronal hole high speed stream.
