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 is transiting the Central Meridian.

Solar activity is expected to remain at very low levels.

Around 22:45UT on 3 September, solar wind speed started a gradual increase from about 330 km/s to its current values around 400 km/s (DSCOVR). Bz varied between -7 and +5 nT, with a negative 1-hour stretch near -6 nT centered on 04:10UT. The direction of the interplanetary magnetic field was variable, being in a mostly positive sector (away from the Sun) after 05UT.

Quiet to unsettled geomagnetic conditions were observed and are expected to continue. On 6 and 7 September, active conditions are possible with the arrival of the co-rotating interaction region (CIR) and wind stream from the negative polarity CH.
