Large-scale traveling ionospheric disturbances over central and eastern Europe during moderate magnetic storm period on 22-24 September 2020

ionosondes located in Juliusruh, Pruhonice and near Kharkiv, and the Kharkiv incoherent scatter radar were employed to study temporal and spatial LSTID signatures at ionospheric heights. Employment of incoherent <...
