X-ray flux remained below B level throughout the period. NOAA AR 2719 revived (Cro, Beta-Gamma) and there is a new region emerging near N7W20 which appears a fairly simple bipolar region. X-ray flux is expected to remain below C level.
No new Earth directed CMEs were observed in coronagraph data.
Proton flux levels were at background values and are expected to remain so.
Solar wind speed declined further to around 360 km/s. A number of sudden density and magnetic field increases occurred since around 6:00UT. These are possibly representing the first signs of the August 20 CME. Total magnetic field grew to 7nT with recently a peak of Bz down to -6nT. Further increases of magnetic field strength can be anticipated with the possibility of periods of persistent Southward magnetic field orientation over the next 24 to 48 hours. Afterwards, Solar wind conditions should recover to nominal.
Geomagnetic conditions were quiet (both local K Dourbes and NOAA Kp 0-2). Active geomagnetic conditions and possibly minor geomagnetic storms must be anticipated over the next 24 to 48 hours.
Today's estimated international sunspot number (ISN): 029, based on 23 stations.
