The extent of propagation afforded by the ionosphere is analyzed during the sunrise period on long east-west paths. During this period the propagation conditions are examined as functions of distance along the path and time. The propagation losses are attributed primarily to absorption in the lower ionosphere and the ground when multiple E-layer modes occur at the eastern end of the paths. Author
