Short summary
We present the dynamics of perturbations during a solar eclipse using rare parameters for eclipse study. Reduction in solar radiation and natural gas heating are the cause of the observed changes. The use of the bottomside F-layer parameters to probe the topside ionosphere established their interrelationship. The implication is that eclipse-caused perturbation could be better explained using some ionosonde parameters.
