A suspected meteor lit up the skies of the Scottish Highlands on Monday, prompting calls to the police from worried witnesses.
A loud boom that shook buildings was also reported.
Footage of the strange event was caught on car dashcams with one showing a bright white object streaking through the sky.
Jenni Morrison told STV News: "It was amazing, I've never seen anything like it. It was like someone had switched a light on."
Police said they received calls around 6.55pm on Monday evening.
STV News weather presenter Sean Batty said: "I've had lots of tweets from around the north and east of the country this evening with people reporting a loud bang and a large flash in the sky. Most tweets have come from around Perthshire, Angus, Aberdeenshire and Moray.
"There are no thunderstorms being reported anywhere in Scotland this evening, therefore this is not due to a flash of lightning.
"My only conclusion would be that this is indeed a meteor which has burned up and exploded during entry into our upper atmosphere.
"The flash of light would be of an extraordinary level, and given tonight's full cloud cover this would have illuminated the whole sky."
The Ministry of Defence said they would not discuss if there was any link to any operations in the area.
