Bulletin

Solar activity was at very low levels. No earth-directed coronal mass ejections (CMEs) were observed in the available coronagraphic imagery. The greater than 10 MeV proton flux was at nominal levels. A small negative polarity coronal hole has transited the Central Meridian.

Solar activity is expected to remain at very low levels.

Solar wind speed continued its gradual increase from an initial 400 km/s to values around 500 km/s by the end of the period (DSCOVR). Bz varied mostly between -6 and +5 nT, with a negative stretch from 21UT till 01UT. The direction of the interplanetary magnetic field was mostly in a positive sector (away from the Sun) until about 09UT, after which it was directed more towards the Sun.

Quiet to unsettled geomagnetic conditions were observed, with Kp recording an isolated active episode during the 00-03UT interval. Quiet to unsettled geomagnetic conditions are expected. Chances on active episodes are likely to increase on 6 and 7 September in response to the expected arrival of the co-rotating interaction region (CIR) and wind stream from the negative polarity CH. A minor storming episode is not excluded.
