Reports and photos of witnessing a strange phenomenon were poured on SNS, and various speculations such as "Is it a meteorite falling?" and "Isn't it a missile?"
This phenomenon, which appeared throughout the city of Jeju, continued for more than an hour.
The identity of the pillar of light that surprised the citizens was none other than a natural phenomenon created by light and clouds.
It is said that the light of the fishing boats floating in the sea was reflected by the clouds.
The Jeju Regional Meteorological Administration explained that the clouds acted as a kind of mirror as the lights of the fishing boats were reflected off the upper clouds 5-6 km high.

The reason why light has a columnar shape is because the upper cloud layer is mainly composed of hexagonal ice particles.
Netizens responded, "It's more beautiful than any artificial light. If you saw it in real life, you'd be enchanted!", "It's so amazing. I thought it was an alien communication."
