Solar X-ray flux remained at background levels throughout the period. The regions on disk were stable or in decay while the region responsible for the C-flares on the previous days, rotating onto the disk in the East, is spotless and remains unnumbered. There is only a slight chance for C flaring over the next 24 hours. Proton flux levels were at background values and expected to remain so. No Earth directed CMEs have been observed in coronagraph data.
Solar wind speed remained slightly enhanced after the CME passage and showed recently the expected increase due to the negative polarity coronal hole high speed stream. Solar wind speed is consequently in the range 620-700 km/s since around 7:15UT. Total magnetic field was in the 6.5-10nT range throughout the period with a variable Bz and a phi angle in the negative sector. Solar wind conditions are expected to remain enhanced over the next 48 hours due to the high speeds stream from a recurrent negative polarity coronal hole. Geomagnetic conditions were quiet to unsettled (both K Dourbes and NOAA Kp 1-3) and are expected to be quiet to active with possibly minor geomagnetic storms as the high speed stream from the negative polarity coronal hole persists.
