Abstract: Ionosonde observations and Faraday rotation measurements were made at Ahmedabad to study the ionospheric effects of the total solar eclipse of 16 Feb. 1980. Data on the eclipse day and control day (mean for 17-19 Feb. 1980) are presented in a comparative way. Decrease in the critical frequencies of E- F1- and F2-layers, viz. foE,foF1 and foF2 and in the minimum frequency fmindetected by the ionosonde, associated with the eclipse are noted. True height analysis of the quarter hourly ionograms shows decreases in the electron densities at various heights, the effects being gradually delayed at higher altitudes. Increase in the height of maximum F2-1ayer ionization (hmF2) and in the semi-thickness of the F2-layer (ym) are noted. A decrease in the total electron content (TEC) derived from the recordings of Faraday rotation at Ahmedabad is found during solar eclipse. No evidence of gravity waves, generated due to the eclipse and propagating in the ionosphere, could be detected from the continuous recording of foF2 or TEC.
