Solar X ray flux remained below B level throughout the period. With a spotless disk, X-ray flux is expected to remain at or below background levels.

The filament eruption reported yesterday was associated with a very narrow and slow CME towards the West as seen by STEREO A COR2. SoHO/LASCO C2 and C3 coronagraph images show a slow and East directed CME. Based on these observations we judge that the ejecta are sufficiently East of the Sun- Earth line and no impact on Earth is expected. There were no other Earth-directed CMEs observed in coronagraph data.

Proton levels were at background values and are expected to remain so.

Solar wind speed has overall decreased to between 350-400 km/s with total magnetic field around a nominal 5nT. Bz was mostly positive and the magnetic field phi angle mostly indicated a negative sector connection with some periods in the positive sector. By the end of the day Solar wind conditions may become enhanced under the influence of a Southern hemisphere coronal hole.

Geomagnetic conditions were mostly quiet to unsettled (local K Dourbes 0-3) with an isolated active period (NOAA Kp 4) after midnight. Geomagnetic conditions are expected to be unsettled with isolated active periods possible.
