Using the data of the observations at auroral observatory Molodezhnaya (Antarctic, L = 6.3), a similarity is found in the shape of the wave packets amplitudes envelope of giant pulsations to solitons. The relation is analyzed between the maximum amplitude (A), the carrier in frequency (f), and the width of wave packets (&tgr;) for 30 cases of observations of the Pg pulsations having the form of separated wave packets. It is shown that the maximum amplitude of wave packets depends linearly on 1/&tgr;¿f1/2. We suggest that some Pg pulsations present nonlinear structures having the properties of solutions.
