Luni-solar variations in f0F2 at four African stations

Abstract

The luni-solar tidal oscillations in f0F2 at Djibouti, Tamanrasset, Lwiro and Nairobi have been examined and the results are presented in the form of percentage amplitude spectra. These show some consistent common features and some important difference between stations. Large lunar controlled percentage perturbations in electron density occur at all stations in the pre-sunrise period.
