RUSSIAN JOURNAL OF EARTH SCIENCES, VOL. 19, ES3002, doi:10.2205/2019ES000661, 2019 ![]() Figure 5. ORB-3 6810 kHz observation of A) arrival angle in the East–West direction (blue) and the North–South direction (green) and B) LOS plasma Doppler velocity. Oscillations are present before HAAW arrival that make possible HAAW induced oscillations difficult to identify. An oscillation near 4.3 s is present in the spectral analysis, but is too obscured by pre-disturbance plasma structure to be visually obvious. Copyright 2019 by the Geophysical Center RAS.
