| The auroral curtain moves, sometimes slowly and sometimes
rapidly, across the sky. Auroral scientists record these movements with a variety of
instruments. Among them is an all-sky camera, which produces circular images of the entire
sky, and a satellite-borne imaging device, which produces global images of Earth.
