Wave propagation analysis of the case 6 shown in Fig. 28 between 06:29:30 and 06:31:00 UT. From the top to the bottom: the magnetic field spectrogram, the electric field spectrogram, the ellipticity of magnetic field, the polar angle θ, and the Poynting vector component along the terrestrial magnetic field normalized by the standard deviation (see text for explanation). All parameters are color-coded according to the scales on the right. The frequency range is from 300 Hz up to 1.2 kHz. In each panel the line just above 600 Hz represents the proton gyrofrequency. The parameters displayed on the abscissa are the time in UT, the geomagnetic latitude and longitude, and the magnetic local time
