NOAA 2585 has a small delta in its main trailing spot and produced several B-class events, the strongest a B8.3 flare peaking at 04:47UT. The two other regions (NOAA 2588 and Catania 28) were quiet. 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 varied mostly between 450 and 510 km/s. Bz fluctuated between -5 and +4 nT. The interplanetary magnetic field (IMF) was predominantly directed away from the Sun (positive). Quiet to unsettled geomagnetic conditions were observed, with an active episode during the 12-15UT interval (Dourbes) and during the 03-06UT interval (Kp).
Quiet to unsettled geomagnetic conditions are expected, with still an active episode possible. There's a small chance that high speed streams from two polar coronal hole extensions (one at +30 degrees and another at -35 degrees) may influence the earth environment from 11 September onwards.
Today's estimated international sunspot number (ISN): 051, based on 22 stations.
