Lights Come On Over Leven.

Looking across the bay from Lundin Links, the lights come on over Leven at dusk.

I think that the bright glow above the skyline is coming from Mossmorran flaring. The Mossmorran NGL (natural gas liquids) fractionation plant is part of the North Sea Brent oil and gas field system located on the outskirts of Cowdenbeath, Fife. Flaring is an essential part of the plant's safety systems.
Mossmorran is around 18 miles away from Lundin Links so imagine how bright it must look nearby!
