Variations in the radial profile of the pressure and distortions of the magnetic field of the magnetosphere in the dark sector near the equatorial plane during the storm of May 29, 2010, are analyzed based on THEMIS data. The position of the pressure maximum during the main phase of the storm is determined. The time dynamics of the pressure maximum is traced during the recovery phase. The time of pressure relaxation to initial values (before the main phase) during the recovery phase are assessed. The coincidence of the positions of the pressure peak maximum and of maximal deviation of the magnetic field from the dipole one is ascertained.
