Local media said that the rare event, called a ‘blue jet’ was a rare meteorological phenomenon.

They said that it involved blue jets occurring in intense storms in the upper atmosphere. With electrical discharge originating at the top of the clouds able to extend towards space, sometimes reaching altitudes up to 50 kilometres in less than a second.

Local media quoted experts as saying that the blue hue comes from stratospheric nitrogen in the atmosphere, setting the bursts of light apart from the white light seen shimmering below the clouds.
