A double sunset is a rare astro-geographical phenomenon, in which the sun sets twice on the same evening from a specific place.
The first published mention of a double sunset which occurred in Leek was made in 1686 by Dr Robert Plot in his book The Natural History of Stafford-shire.
The spectacle was last reliably witnessed, and filmed, from the churchyard belonging to the parish church of St Edward the Confessor in 1977.
Historically, it appears that a double sunset is very rare, so we may wonder what is going on because people around the world are currently witnessing double sunsets.
That the phenomenon is not an illusion proves the last double sunset which was spotted from North Carolina as Brian witnessed a bright East and West horizons after sunset on July 15, 2017 as you can see the below video.
