Abstract: Ionograms and amplitude measurements at 2.7 MHz were taken during the solar eclipse of 16 Feb 1980 at Gauhati University. Abnormally low absorption observed during the maximum eclipse effect condition has been linked with formation of distortions or curvatures in the reflecting surface produced by gravity waves generated during eclipse. The wavy variation pattern of foF2, foF1, etc. seen at this station supports the theories of formation of such waves. The amplitudes of undulations in foF1 and fmin have been found to increase when that of foF2 is decreased. Along with this the ionization density of F1-layer is also lowered when that of F2-layer is increased. The amplitudes of undulations and ionization densities of F1 and F2-layers suggest the migration of ionization from lower to upper layers and the presence of gravity waves.
