The Sun was spotless. Solar activity was at very low levels and is expected to remain so.

The greater than 10 MeV proton flux was at nominal levels. The greater than 2 MeV electron flux reached high levels, with a maximum of 10200 pfu at 16:00UT. The 24h electron fluence was at moderate levels. There's a chance that the electron flux and 24h fluence reach high levels during the next 24 hours.

No earth-directed coronal mass ejections (CMEs) were observed in available coronagraphic imagery. A slow CME (186 km/s) first observed by LASCO/C2 on 7 September at 21:24UT seemed to have its source at or just beyond the west limb and has apparently no earth-directed component.

Solar wind speed was on a declining trend, from about 370 km/s initially to 315 km/s at the end of the period (DSCOVR). Bz was steady between -3 and +3 nT. The interplanetary magnetic field (phi angle) was predominantly directed away from the Sun (positive sector).

Geomagnetic activity was at quiet levels and is expected to remain so.
