Bülletään

Solar activity was very low with X-ray flux remaining below B level and no spots on the visible disk. This is expected to remain so over the next days.

This morning (September 27), a filament located around S26E11 erupted slowly, but available coronagraph images seem to indicate that there is no CME associated.

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

Solar wind conditions were slowly moving towards the nominal regime. Solar wind speed saw a general decreasing trend from around 450 km/s to 410 km/s currently. Total magnetic field was 2-6nT with Bz variable. The magnetic field phi angle was in the positive sector. Solar conditions are expected to become and remain nominal over the next days.

Geomagnetic conditions were quiet to unsettled (NOAA Kp as well as local K Dourbes 1-3). Generally quiet conditions are expected over the next days with isolated unsettled conditions possible.
