Solar activity was at very low levels. NOAA 2683 (Catania 57) produced all of the low-level B-class flaring during the period, a B9.8 flare peaking on 06 October at 16:34UT being the strongest. It was also the source of a Long Duration B4.6 flare peaking at 00:28UT. Eruptive activity to the north and northwest of NOAA 2682 (Catania 56; now beyond the Sun's west limb) resulted in 2 coronal mass ejections (CMEs) observed by SOHO/LASCO C2 at resp. 09:12UT and 12:36UT on 06 October. None of the observed CMEs had an earth-directed component. The greater than 10 MeV proton flux was at nominal levels.

Quiet flaring conditions are expected, with a small chance on an isolated C-class flare.

Solar wind was enhanced, probably influenced by the weak particle stream from the small negative equatorial coronal hole (CH). Solar wind speed reached a maximum speed around 470 km/s (DSCOVR) at the beginning of the period, gradually declining to its current values near 410 km/s. Bz oscillated between -5 and +6 nT. The interplanetary magnetic field was mostly directed towards the Sun. The extension of a positive polar CH started its transit of the Central Meridian early on 07 October and may influence the earth environment around 10-11 October.

The geomagnetic field was at quiet levels. Quiet to unsettled conditions are expected, with a small chance on an isolated active interval.
