NOAA 2585 shows signs of decay. It produced the only two flaring events of the period: a B9.2 flare peaking at 18:17UT, and a B6.4 at 09:12UT. A potentially active region is about to rotate over the east limb. A 40-degrees long filament in the northwest quadrant is quiet. A slow coronal mass ejection (CME) was observed in LASCO/C2 imagery on 04 September starting at 13:36UT. It was most likely associated with a small reconnection event near S15W20 around 08:00UT. The CME seems to be mainly directed south of the ecliptic with no obvious earth-directed component.
C-class flares are possible, with a small chance on an isolated M-class event.
Solar wind parameters seem to indicate a weakening influence of the coronal hole (CH) high speed wind stream (HSS), with speed declining from initial values near 700 km/s to its current 600 km/s. Bz fluctuated between -5 and +5 nT, with the interplanetary magnetic field (IMF) directed away from the Sun (positive). Mostly unsettled to active geomagnetic conditions were reported by Dourbes. Kp reached minor storm levels 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 2 days as the effects of the CH HSS are expected to further decline.
Today's estimated international sunspot number (ISN): 031, based on 17 stations.
