sentences:  At an elevation between about 35°–50°, the sides form two distinct, downward-drooping "lobes" outside of the 22° halo.As the sun or moon rises higher (between c. 50°–70°), the drooping diminishes towards a more regular oval shape.At an elevation of c. 70° or more, the shape of the circumscribed halo approaches a circle, and as such becomes nearly indistinguishable from the 22° halo, only to be identified by its tendency to show more saturated colors than the latter.
