The response of the magnetopause surface to time-varying solar wind dynamic pressure is examined. We argue that to a first approximation the magnetopause surface may be considered as analogous to an elastic membrane. Upon displacement from equilibrium resulting from a change in applied external pressure. it moves to a new equilibrium under the equation of motion of a forced. https://www.roneverhart.com/Under-Armour-Hustle-5-0-TEAM-Backpack/
