X ray flux remained below B level throughout the period and this expected to remain so as the visible side of the Sun turned spotless

West of the decayed NOAA AR 2719 an eruption occurred around noon August 22 as evidenced from EUV images with e.g. a dimming in SDO/AIA 193 at 12:30 UT. Currently available SoHO/LASCO C2 images do not show any obvious signs of a possibly associated Earth bound CME.

Proton flux levels are at background values and are expected to remain so.

Solar wind declined further with speed dropping to around 400 km/s and a nominal magnetic field of 2-5nT. The phi angle which was stable in the negative sector before the period but shifted suddenly into the positive sector at the start of the period. Solar wind conditions are expected to become enhanced from between noon August 24 and noon August 25 with the possible arrival of the August 20 CME. Effects in terms of solar wind speed should be small but the magnetic field may see significant effects of the slow passing cloud.

Geomagnetic conditions were quiet to unsettled (K Dourbes 1-3 and NOAA Kp 0-2) and are expected to remain so for at least the remainder of the day. Should the August 20 CME carry significant Southward magnetic field, minor geomagnetic storms are possible from noon August 24 onwards.
