GEGENSCHEIN (Ger. gegen, opposite, and schein, shine)  , an extremely faint luminescence of the See also:sky, seen opposite the direction of the See also:sun . See also:Germany was the See also:country in which it was first discovered and described . The See also:English rendering " See also:counter-glow " is also given to it . Its faintness is such that it can be seen only by a practised See also:eye under favourable conditions . It is invisible during the greater See also:part of See also:June, See also:July, See also:December and See also:January, owing to its being then blotted out by the See also:superior See also:light of the Milky Way . It is also invisible during moonlight and near the See also:horizon, and the neighbourhood of a See also:bright See also:star or See also:planet may interfere with its recognition . When none of these unfavourable conditions supervene it may be seen at nearly any See also:time when the See also:air is clear and the depression of the sun below the horizon more than 200 .
