Abstract
In this work, we describe the wave ionospheric disturbance connected with large scale traveling disturbance registered using oblique incidence data over Siberian and Far Eastern regions on April 20, 2018. We analyze diurnal variations of maximum observed frequency (MOF) of HF signals. MOF variations over the paths studied have reached 10 MHz during the main phase of the magnetic storm. The wave disturbance period is 2-3 hours.
