Using Swarm ESA's constellation of satellites dataset we determined the current position of the North and South Magnetic Poles. We also analyzed the spatial shift during magnetic quiet and disturbed days, taking into account the possible relation of the pole position and displacement with the IMF east-west component, a parameter which can create a magnetospheric asymmetry about the noon-midnight meridian. We compared these results to the ones using ground observations at the same time interval and back in recent historical times for tracking its migration path over the surface of the Earth.
