Abstract : Results are presented of scintillation observations made during a two and a half year period at Lerwick in the Shetland Islands using more than 19000 passes of NNSS satellites. Examples of scintillation morphology, in the region near the scintillation boundary and the F-layer trough, for both amplitude and phase are discussed using exceedence levels for the S sub 4 and sigma sub psi indices respectively. The equatorwards advancement of the scintillation boundary in response to enhanced solar activity during the increasing phase of the solar cycle is shown to be a dominant feature in the observations.
