Solar activity was at very low levels and is expected to remain so. SDO/HMI's latest white light images indicate some small spots are developing in old active region NOAA 2766, located near N05W60.

The significant coronal mass ejection (CME) associated with the filament eruption near the NW solar limb early on 09 July does not seem to have an earth-directed component. The faint and slow-moving (250 km/s) CME associated with a long-lasting filament eruption in the SW solar quadrant was barely visible in SOHO's coronagraphic imagery. In view of its width (about 110 degrees in LASCO/C2 at 09/13:25UT July) and the source location near S30W15, there's a small chance on a glancing blow from this CME late on 13 but more likely on 14 July. No other earth-directed coronal mass ejections (CMEs) were observed in available coronagraphic imagery.

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.

Solar wind speed varied between 300 and 340 km/s, ending the period near 330 km/s (DSCOVR). Bz varied between -4 and +4 nT, with a negative stretch from 04-09UT. The direction of the interplanetary magnetic field (phi angle) was mostly directed away from the Sun (positive sector).

Geomagnetic activity was at quiet levels, with an unsettled interval (06-09UT) recorded by Dourbes. Geomagnetic conditions are expected to be mostly quiet on 10-11 July. Unsettled intervals are possible on 12-13 July from coronal hole wind stream effects, and on 14 July from a glancing blow from the 09 July CME. An isolated active interval is not excluded.
