Solar activity was at very low levels. The Sun remained spotless. 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 trans-equatorial extension of the positive polarity coronal hole (CH) at the Sun's north pole has started its transit of the Central Meridian early on 7 September.

Solar activity is expected to remain at very low levels.

Solar wind was steady at nominal values, until the arrival of the co- rotating interaction region (CIR) and wind stream from the negative polarity CH. The CIR arrived around 19:30UT, with solar wind density increasing from about 5 to 24 particles/cm3 by midnight, and the interplanetary magnetic field changing direction from mostly away to mostly towards the Sun. Solar wind speed started to increase from 02:30UT onwards, reaching a maximum near 510 km/s by 08UT, and is steady since then (DSCOVR). Bz varied between -4 and +4 nT, being mostly positive, and with a strong positive episode near +10 nT from 04UT till 07UT, with little interruption.

Due to the predominately positive Bz, mostly quiet geomagnetic conditions were observed. Quiet to unsettled geomagnetic conditions are expected, with a decreasing chance on an active episode as the CH wind stream is passing by.
