An analysis of phase path fluctuations occurring in the F-region of the ionosphere as measured by 5.6 MHz fixed frequency pulsed vertical transmissions during a solar eclipse is presented. The phase path increase began with the eclipse and continued until 7 min after total obscuration of the sun. Comparison with data from a normal day showed the eclipse readings to be excessive, followed by a decline to normal levels. The large amplitude periodic fluctuation displayed three maxima and two minima with an oscillatory pattern corresponding to an upward and downward layer motion of the atmosphere. Smoothing the curve of the increases by linear regression and using a classical acoustic formula for the amplitude of a damped sinusoidal waveform produced a figure which matched well with the observed phase path for three cycles of the recorded oscillation.
