The earth is still under the influence of the high speed wind stream from the equatorial coronal hole. NOAA Kp reached values of 5,6 during the most intensive period which has passed. The solar wind speed is currently still elevated at 700 km/s, the southward component of the IMF is oscillating between + and -5nT. Geomagnetic conditions are expected to return to quiet levels soon.
