Solar activity was at very low levels and is expected to remain so. The Sun was spotless. Two filament eruptions took place resp. around 20UT near S35W10 and shortly after midnight near N45W50. Coronal dimming was observed in both cases. STEREO-A coronagraphic imagery indicates two related CMEs: a faint one around 02UT (250 km/s) and a more solid and faster one around 03:30UT (360 km/s). Based on the limited imagery, at least the first CME may have an earth-directed component. Geomagnetic effects are possible around 13 July, but standing-by further imagery for a more accurate assessment.

The greater than 10 MeV proton flux and the greater than 2 MeV electron flux were at nominal levels during the last 24 hours and are expected to remain so.

No earth-directed coronal mass ejections (CMEs) were observed in available coronagraphic imagery.

Solar wind speed continued its gradual decline from about 370 km/s to its current values near 325 km/s (DSCOVR). Bz varied between -4 and +3 nT, being mostly negative after 03UT. The direction of the interplanetary magnetic field (phi angle) was directed away from the Sun (positive sector).

Geomagnetic activity was at quiet levels. Geomagnetic conditions are expected to be mostly quiet, with a chance on an unsettled interval later today or early on 10 July if a glancing blow from the 5 July CME would materialize.
