Solar activity was at low levels. NOAA 2683 (Catania 57) produced several low-level B-class flares and an isolated C1 flare peaking on 05 October at 13:41UT. The region has lost most of its opposite polarity spots south of the main spot. NOAA 2682 (Catania 56) showed some activity north of its main spot from 08UT onwards (x-ray flux enhancement, no flare). No earth-directed coronal mass ejections (CMEs) were observed in available coronagraphic imagery. The greater than 10 MeV proton flux was at nominal levels.
Quiet flaring conditions are expected, with a small chance on another isolated C-class flare.
Solar wind speed continued its gradual increase from its initial 370 km/s to current values around 450 km/s (DSCOVR). Bz oscillated between -8 and +7 nT, being predominantly negative during the 19UT-03UT interval. The interplanetary magnetic field was mostly directed towards the Sun.
The geomagnetic field was at quiet to unsettled levels, and is expected to remain so. The particle stream associated with a small negative equatorial coronal hole is still expected to arrive at Earth, either later today or tomorrow 07 October. This may increase the likelihood on an active geomagnetic episode.
Today's estimated international sunspot number (ISN): 025, based on 24 stations.
