Dozens of you captured the spectacle as the latest in lighting technology created a host of effects in the night sky on Castle Hill.
Light expert James Bawn lit up the iconic Victoria Tower to mark the start of UNESCO’s International Year of Light and Lighting Technologies.
His impressive new beams rose hundreds of feet into the clouds, creating a spooky scene akin to an alien invasion and there's another chance to see them from 5pm to 11pm tonight.

James, who last lit the tower for Hypervelocity to celebrate the Tour de France, said people would be able to see them across most of south Huddersfield.
“It’s been great,” he said. “We’ve just been having a play and seeing what they’re capable of.
“It’s brand new technology that’s quicker, lighter and more powerful.
“We just pointed one at Emley Moor Mast and it was catching the top of it.
“The optics on these compared to normal search lights are incredible.
“A few people have come up to watch it with us but the best view is probably from a distance.
“I’ve had tweets from Bolster Moor so I know people saw them there.
“I’m very impressed.”
