Geomagnetic conditions have reached moderate storm levels globally (Kp 6) and minor storm levels locally (K_Bel 5), due to the ICME that arrived yesterday (solar wind speed up to 600 km/s and interplanetary magnetic field up to 22 nT and Bz down to -17 nT) and probably also some effects from a high speed solar wind stream. More disturbed conditions can be expected in the next 24 hours.

A partial halo CME with angular width around 150 degrees was first seen at 11:12 UTC on 18 September by LASCO-C2. The CME most likely originated (the eruption signatures are weak) in the vicinity of NOAA AR 3436 in the NW quadrant, it was slow (around 300 km/s) and mostly directed to the NW. Nevertheless a glancing blow at the Earth can not be discarded on 22 September.
