Fig. 4

An expansion of the Geotail observation for 3.5 hours from 13:30 to 17:00 UT. Energy-time spectrograms for a dawnward-going ions, b sunward-going ions, c duskward-going ions, d antisunward-going ions, e ion density, f ion temperature, g ion velocity in GSE, h power spectral density of \(V_X\), and i magnetic field in GSE are plotted. The former rectangle between 14:30–15:10 UT corresponds to the period with detailed explanations of the boundary properties (See main text), while the latter between 16:30–16:46 UT corresponds to the period expanded in Fig. 5
