The solar wind speed remained between 400 and 500 km/s. The magnetic field magnitude was about 5-8 nT, with a fluctuating north-south component. Geomagnetic conditions were mainly quiet (K=0-2) to unsettled (K=3), with a time slot of active conditions (K=4) at 9h UT both at local (Dourbes) and global (NOAA estimated Kp) levels. Mainly quiet to unsettled conditions are expected to continue.
