Abstract

We have observed numerous superior mirages at great distances, ranging from 70 to 100 km. Such mirages are well known and immediately recognised, because they do not look significantly different from short range mirages; but it appears that no one has published an analysis that actually identifies the appropriate atmospheric conditions. Three models developed¹ to reproduce an observation will be presented here for comparison and discussion. Only one of them seems reasonable.
