This is the strange moment the sky seemed to split between light and darkness, leaving locals baffled.
The images show the skyline divided into night on one side and day on the other in Mandaue City, Philippines, on October 10.
One part seemed illuminated by the evening rays while the other had already plunged into darkness.
This rare phenomenon is believed to be a split sunset, a spectacle that occurs when light disperses as the sun passes over the horizon.
Viewer Leylan Romarate said he recorded the scene without using a filter, a claim supported by video metadata showing the original file, location and device.

He can be heard saying in the video: “There’s a line right there.” It is day and night.
‘What is this? There’s no filter on my phone’s camera.’
Speaking after capturing the strange phenomenon, Leylan said it was the first time he had seen the sky like this.
He added: “A lot of people saw this too, not just me. Is this something natural? I’ve never seen that happen before.
Split sunsets occur when half of the sky receives daylight while the other part is plunged into darkness.
The line between the two is known as the ‘terminator’ or ‘twilight zone’, which is a moving line that separates the illuminated or day side of the planet from its night side.
The division occurs due to the planet’s rotation, creating a gradual transition between day and night.

This rare phenomenon is believed to be a split sunset: a spectacle that occurs when light disperses as the sun passes over the horizon.
Split sunsets are generally a result of atmospheric conditions and occur when two contrasting air masses are present.
Air masses can have different levels of humidity, pollution, and temperature that impact how light rays scatter as they pass through them.
This, in turn, results in the sky splitting into two different colors.
It comes after British skywatchers were left baffled in August by an almost apocalyptic sight in the sky.
Across the country, people watched in confusion as the sky, sun, and moon turned a deep blood red.
Keen skywatchers flocked to social media to share photos of the strange event, with one confused commenter calling it “totally crazy and creepy.”
Experts explained that this phenomenon is due to forest fires more than 4,000 miles away in North America.
Met Office spokesperson Andrea Bishop told MailOnline: “Vivid and dramatic looking sunrises and sunsets were observed in the UK, in part, due to a layer of bushfire smoke that has been present in the upper atmosphere this weekend”.
He added: “Smoke particles from wildfires across the Atlantic have been carried by the jet stream.”
