Magnetic field data from a ETS-VIII, b THEMIS-E, c THEMIS-D, d QZS-1, e CHD, f TIK, and g KTN. The satellite magnetic field data are subtracted by the Tsyganenko 89 model field at \(K_p=0\). The ground magnetic field data are subtracted by values averaged by their values in the plotted interval. The MLTs are AACGM MLTs at 15:15 UT. (h) AACGM magnetic latitude at 100 km in altitude of ionospheric footprints of satellites and ground observatories
