Solar activity is very low, no C-class flares in past 8 days. Geomagnetic conditions were quiet to unsettled in Dourbes, while there was one period of active conditions at planetary levels (Kp=4) from 15:00 UT to 18:00 UT on September 13, due to the influence of the coronal hole related fast solar wind. The Earth is still under the influence of this fast stream, but quiet to unsettled conditions are expected for the next 48h.
