Solar activity was at very low levels and is expected to remain so. The solar disk was spotless. Old active region NOAA 2766 was the source of two A2 flares peaking on 11 July at resp. 10:20UT and 20:50UT. Coronal dimming and weak EIT waves were observed, but the associated CMEs were very faint.

No 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 was on a slightly declining trend from initial values near 330 km/s to 290 km/s by the end of the period (DSCOVR and ACE). Bz varied between -3 and +1 nT. The direction of the interplanetary magnetic field (phi angle) was mostly directed away from the Sun (positive sector).

Geomagnetic activity was at quiet levels. Geomagnetic conditions are expected to be mostly quiet, with unsettled intervals 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.
