Short summary
Short summary
The contributing influence of SSW to regional ionosphere through chaos theory is examined. We found that ionospheric chaos is more pronounced in the European sector compared to Africa sector during SSW. Evidence of orderliness behavior in regional ionosphere of African sector was observed. Finally, we noticed that after the peak phase of SSW, ionospheric chaos is found to be more pronounced.

Short summary
Short summary
This paper describes chaos and dynamical complexity to reveal the state of the underlying dynamics of the ionosphere on a daily basis. This is to show the daily/transient variations of chaoticity and dynamical complexity so as to reveal the degree of changes that occur in the ionospheric process and dynamics from one day to another. This paper will point the space science community in the direction of the use of chaoticity and dynamical complexity as indices to describe the process and dynamics.
