Ray Majoran got a text message from a friend one evening last month. His friend was driving into London and saw what appeared to be light pillars shooting up from the city into the night sky.
Majoran, who owns an advertising agency, grabbed his camera. He jumped into his own car and started searching for the strange lights.
The images Majoran captured that night have since appeared in the Washington Post with the headline: 'These ice pillars make it look as if this Canada town is being abducted by aliens'.
Well, London is far bigger than a town. And no aliens were spotted. Still, Majoran describes what he saw that night as "epic".
"When you are out there looking at it, if you don't know what to make of it, it's pretty crazy," Majoran said in an interview on CBC Radio's London Morning. "My mind was pretty blown."
Majoran has travelled the world taking photographs for his personal website. He's just returned to London from a trip to India.
He says he had heard about light pillars appearing in other countries and that the weather phenomenon had even been seen in the London area.
So what causes the sky look like that?
"It actually is little suspended hexagonal ice crystals that are just hovering in the air. They're not actually landing, it's almost like an ice frost," said Majoran.
The crystals take any light source and reflect it upwards for kilometres, according to the photographer.
Majoran says the different colours you see in the photos correspond to different light sources: for example, the blue tones likely come from LED lights.
What's more, Majoran promises the shots are strictly #nofilter.
"As I showed these photos to my friends and they were like 'Is that photoshopped?' And I said, 'No it's not, and here is a picture unedited from my iPhone that I just captured,'" he said.
"It was just phenomenal, and you could see it with your naked eye."
