Double sunset

A double sunset is a rare astro-geographical phenomenon, in which the Sun appears to set twice in the same evening from a specific viewing-point. A double sunrise may also occur in a similar situation. Such phenomena may have been regarded as significant in prehistoric times, and double sunsets have been discussed in the context of archaeoastronomy by researchers such as Alexander Thom.
