Description	The ionospheric variability in the period range 15 minutes to 3 hours is studied in time series consisting of electron densities measured in Pruhonice observatory (49.9N,14.5E -vertical ionospheric sounding with repetition time 5 minutes).Data (figure 1) from HIRAC campaign -23 April to 29 April 2001 of rapid sequence sounding (5 minutes repetition time)are used to detect wave-like structures in the F region over specified area. Wave-like variations were studied during quiet and disturbed days.Quiet (Ap<7)were on 24 April and 26 April 200,disturbed on 28 April 2001 (Ap=40,minor storm).The HIRAC campaign was provided in period of solar cycle maximum characterized by smoothed sunspot number R12=108.One-dimensional time series (diurnal variation of electron concentration) are represented into a Time and Period space thanks to the Continuous Wavelet Transform (Torrence and Compo,1998).The wavelet decomposition enables us to study the onset and the time and frequency developments of the wave-like structure The ionospheric variability in the period range 15 minutes to 3 hours is studied in time series consisting of electron densities measured in Pruhonice observatory (49.9N,14.5E -vertical ionospheric sounding with repetition time 5 minutes).Data (figure 1) from HIRAC campaign -23 April to 29 April 2001 of rapid sequence sounding (5 minutes repetition time)are used to detect wave-like structures in the F region over specified area.
