Abstract : An investigation of the apparent horizontal ionospheric movements in the lower E-region of the ionosphere is desribed. For the investigation, nighttime observations were made over a period of one year, using the spaced-receiver method, at a frequency of 300 kc on the campus of the Penns lvania State University. The data obtained from the observations were analyzed using correlation techniques in order to observe the effects of random variations and anisotropy of the diffraction patterns. Experimental results are presented under the two main subjects of the apparent ionospheric movements and the spatial properties of diffraction patterns. The former includes the drift and random velocities; the latter, the axial ratio, tilt angle and structure size of diffraction patterns. The determination of solar semi-diurnal components of the drift velocity is given in detail. (Author)
