Bülletään

Solar X ray flux remained below B level throughout the period. There are no spotted regions on disk and X-ray flux is expected to remain at background levels.

No Earth-directed CME's were detected in coronagraph images.

Solar high energy proton fluxes were at background levels and are expected to remain so.

Solar wind conditions have seen the expected decline of the high speed stream. Solar wind speed decreased from just under 550 km/s to under 450 km/s. Total magnetic field was stable around 4nT with a variable Bz component. Solar wind conditions are expected to further decline over the next days.

Geomagnetic conditions were quiet (NOAA Kp and local K Dourbes 0-2) and are expected to remain quiet over the next days.
