There are currently three numbered sunspot regions on the visible disc. Very low solar activity is expected for the next three UT days, 07-09 August. No Earthward-directed CMEs were observed in the available coronagraph images during the last 24 hours. During UT day 06 August, the solar wind speed range was 400 km/s to 530 km/s, in response to coronal hole effects. The total IMF (Bt) range was 2-6 nT, and the north-south IMF component (Bz) varied mainly between +3/-3 nT. The outlook for today (UT day 07 August) is for the solar wind to continue on its gradual decline towards the nominal level. Mostly nominal solar wind conditions are expected on UT day 08 August.
