Strange 'lasers' were seen by hundreds of people shining for miles over Liverpool on Friday night.
The weird lights cast different colours into the night sky between 6pm and 7pm when several residents reported seeing them.
People in Fazakerley, Aintree and West Derby said the beams were very clear and visible but they weren't sure where they were coming from.
One woman contacted the ECHO and said they could be seen shining over her home near Longmoor Lane in Fazakerley.
She said: "The lights are very bright and they have been flashing on and off for the last 10 minutes.
"I'm not sure where they are coming from but I can see them shooting up from behind the houses across the road."
Another reader, who lives in West Derby, said his neighbours had also reported seeing them and were curious about where they were coming from.
He said: "Can anyone please explain the strange lights over West Derby tonight?
"I seen it at around 7pm and loads of people in my area are reporting the same occurrences."
Photographer Andy Teebay located the source of the light beams at Aintree Racecourse, where a police van was stationed at the gate.
The lights were being shone at the sky from the site on the old racetrack near Beechers Brook but it is not clear why.
Andy said: "I followed the lights to Aintree Racecourse.
"They were on the old racetrack near Beechers Brook.
"The police turned up and spoke to a guy in a van, I think he was security."
It is not yet clear why the race course decided to shine the lights tonight.
Merseyside Police were contacted for information.
Aintree Race Course were also called to clarify what was happening but have so far not responded.
We will bring you more information when we have it.
