Yes on this occasion it moved quite quickly. Hard to describe but the swirls move like the speed you might be able to stir something in a bowl with your hands. Then overlayed on that there is like an electromagnetic pulsing which lights up and dims sections of the aurora . Perhaps like a faulty TV flickering on and off . You don’t see this in timelapes as it’s very quick ( pulsing at 10 times a second perhaps ) . There is some real time video footage from some of the new super high iso Sony video cameras that show it.
