A spotless Sun resulted in X-ray flux remaining at background levels and this is expected to remain so over the next days. No Earth directed CME's have been observed in coronagraph data. Proton flux levels are at background levels and are expected to remain so.
Solar wind conditions were dominated by the high speed stream associated to the transequatorial extension of the Southern polar coronal hole. Solar wind speed continued its rise in solar wind speed, that set in late in the previous period, to reach velocities between 650-750 km/s for most of this reporting period. Total magnetic field was enhanced to about 12nT before dropping to nominal 5nT levels around 22:00UT. Bz was variable during the period with occasional negative peaks down to almost -10nT. The phi angle showed the expected negative sector connection. Solar wind speed is expected to remain enhanced over the next 24-48 hour but gradually starting to decline later today. Geomagnetic conditions were mostly active (NOAA Kp 3-4, local K Dourbes 2-4). Active periods are expected to continue to occur with also minor storm levels possible over the next 24-48, but under a generally decaying trend.
