Skies above the West Midlands were illuminated pink in stunning scenes as Britain was battered by Storm Goretti.
Residents living in Birmingham were treated to a dazzling shade of pink, with the vista visible from across the wider county.
There was some speculation the lights were a form of aurora borealis caused by the storm.
However, the actual reason was much more grounded, actually coming from Birmingham City's St Andrew's football ground in Bordesley.

The stadium uses LED lamps to help the grass on the pitch recover faster, particularly when wet weather makes it more vulnerable to damage.
Meteorologists said cloud cover and falling snow meant the sky could be more reflective, meaning the light from the LEDs reflected upwards.
Hednesford Town Football Club said they had a similar phenomenon earlier this week.
A spokesman said they were, "helping the grass grow and recover, keeping us ready to chase three points, not the aurora".

Grahame Madge, Met Office spokesman, said: "The blue wavelengths of light are more easily scattered by snow or water droplets allowing the longer wavelengths – such as red and orange – to get through.
"This can have the effect of turning colours more pink or orange."

The Met Office said on Friday morning that Storm Goretti "continues to cause problems" as a mixture of rain, sleet and snow batters some areas.
Meteorologist Alex Deakin said the storm will continue to clear throughout the day, but many still face a "wet, cold, miserable day."
Cornwall Council advised residents to avoid travelling on Friday morning, saying: “A large number of roads are still closed due to fallen trees, downed power lines and debris.
"Our teams are working around the clock to clear them and we ask that you give crews the space they need to carry out urgent repairs safely."
