Bülletään

X-ray flux remained below B level throughout the period. The Sun is spotless and no flaring is expected.

No Earth-directed CMEs have been observed in coronagraph data.

The proton flux levels were at background values and expected to remain so.

Solar wind showed the expected enhancements under the influence of a high speed stream from an extension of the southern polar coronal hole. Since midnight, Solar wind speed increased from 350km/s to 460 km/s. Total magnetic field reached a peak value of 11nT in the compression region, with Bz around -10nT for a while. The magnetic field phi angle was in the negative sector throughout the period. Solar wind speed is expected to rise further to a maximum of between 500-600 km/s over the next 24 hours before starting a slow return to background values.

Geomagnetic conditions reached active levels (NOAA Kp=5 for the 6-9UT period, while local K Dourbes remained 0-3). Unsettled to active conditions are expected over the next 24 hours before returning to quiet to unsettled conditions.
