  Alpenglow \Al"pen*glow`\, n.
     A reddish glow seen near sunset or sunrise on the summits of
     mountains; specif., a reillumination sometimes observed after
     the summits have passed into shadow, supposed to be due to a
     curving downward (refraction) of the light rays from the west
     resulting from the cooling of the air.
