This shift at night is substantially more prominent, than in day time. The Dst and the PC indices of the magnetic field variations for the same storm are shown at the bottom. The location of the magnetic midnight in each station is marked by triangle. Figure 2 . Arrows mark the latitudes of the eastward electrojet center.
