Meteor sightings: Your stories
Police forces in England and Scotland have received a number of calls reporting what is believed to have been a meteor.
Reports of a "bright light" and an "orange glow" came in across Britain at about 2140 GMT on Saturday amid fears a plane had crashed.
BBC website readers have been sharing their stories and video capturing bright lights in the sky.

I saw the fireball, it moved slowly almost perfectly horizontally across my line of vision from left to right, it wasn't going downwards at all. It was very large and made orange lights. I didn't see any blue or green light so perhaps I caught it later on. At the start on the left the fire was flaring out and making a sort of jet plane shape it really did look like an aeroplane on fire, especially with the speed, the fire lessened and about 15 seconds later had burnt out. It was the most amazing thing I've ever seen and probably ever will. Daniel Shepherd, Wrexham, Wales
My wife and I saw it from our lounge that overlooks Glasgow Airport. We thought it was a plane in trouble but realised it was travelling too fast and there was no noise. It was a bright ball with what looked at first to have two tails but as it went by it looked like it only had one long tail. In all we saw it for about 30 to 40 seconds. I have seen things like this before but not so close up. It was fantastic and we will be talking about this for some time to come. Robert Moss, Glasgow, Scotland
I saw this beautiful sight tonight around 2145 GMT in Edinburgh. It was totally breathtaking. A huge ball of fire with beautiful white tails. My partner and I weren't sure what it was but got to watch it travel northeast over Edinburgh for around 25 to 30 seconds. I thought this was unusual for it to be in sight as long as it was.
