Multiple witnesses saw ten light pillars in the Busan sky in South Korea on the last three nights. They remained in the same place over time. The best explanation from local authorities is that these are caused by refraction through ice crystals in the clouds of strong lighting from local squid fishing boats.
One person said, (translation): “It’s growing in convex lens form. So this is not an object or something, but I thought it was where the light was reflected or something.”
Light attracts thousands of squid
Squid feed mainly at night and are attracted to light, which is why public piers are good locations for anglers. Hungry squid lurk in the dark fringes near patches of lighted water and then dart into the bright area in pursuit of food such as young herring and other small fishes.
Because a boat isn’t needed and jigging equipment is reasonable, squid-jigging is one of the most inexpensive ways to catch squid. Anglers should take a camping lantern or flashlight of significant size for unlit locations.
