Solar X-ray flux has been below background (B) level throughout the period. There are no spotted regions on disc and X-ray flux is expected to remain at or below background (B) values.

There were no Earth directed coronal mass ejections observed in coronagraph data.

The greater than 10 MeV proton flux was at background levels over the past 24 hours. It is expected to stay at background levels for the next 24 hours. The greater than 2 MeV electron flux was at nominal levels over the past 24 hours and is expected to remain so over the next 24 hours.

Another low latitude coronal hole with positive polarity is currently rotating over the central meridian in the Northern hemisphere (It is currently not connected to the polar coronal hole). It's impact on near Earth Solar wind may be expected on August 28.

Solar wind conditions were close to nominal. Solar wind speed decreased from close to 400 km/s at the start of the period to under 350 km/s presently. The magnetic field strength hovered around 5nT and remained at that level. The magnetic field phi angle was mainly in the towards sector. There are hence no signs yet of the expected Solar wind enhancement, due to the possible influence of a high speed stream from the extension of the Northern (positive polarity) polar coronal hole. But, it may still set through in the next 48 hours. Afterwards, from August 28 onwards, we may see again some enhancement related to the coronal hole currently transiting the central meridian.

Geomagnetic conditions were quiet (both NOAA Kp and local K Dourbes 0-2). Geomagnetic conditions are expected to be mostly quiet to unsettled, with some isolated active periods not excluded depending on the strength of the expected Solar wind enhancements.
