This is a composite of north polar projection maps produced by Gerald Eichstadt from images 13, 15 & 17. By enhancing the terminator and blending 3 maps, noise is much reduced and the reddish cloud ridges of the North Polar Cyclone stand out clearly. Three of the circumpolar cyclones are splendidly shown, and the edges of two others are just visible on the terminator. --John Rogers.
