ABSTRACT. Auroral arcs (curtains) are extremely thin. A calculation of the minimum-possible arc thickness is presented; this minimum thickness is found to be about 9.5 m. Four requirements for designing an optical system that can image the thinnest curtains are discussed: 1) angular resolution, 2) t...
