A Durham Police spokeswoman said a number of calls came in around 9.45pm from concerned members of public who had seen a "bright light or a fire in the sky" and believed it may have been incidents involving an aircraft.
"It has been confirmed with air traffic control that there are no incidents of aircraft in difficult and nothing registered on radar," she said.
"The sightings are believed to be either an asteroid burning out or similar which has been restricted to the upper atmosphere only."
Grampian Police said reports of people seeing a "flare or a bright object with a tail" were received from across the region.
And Dumfries and Galloway Constabulary said numerous calls were made about a "large ball of fire in the sky" across Annandale and Eskdale. One user wrote on the force's Facebook page: "It was awesome to see! Really big and bright!"
