A Lincolnshire Echo reader has sent in a video of a strange light travelling across the sky in Lincoln.
Gail Phillips and her husband were looking for the International Space Centre in the sky above Birchwood at around 10pm last night.
They thought they had spotted it when a small light appeared in the sky.
"I was looking for the international space with my husband and thought the light was it but then it started moving in different directions," she said.
"We saw it (the space station) going across the sky, then I spotted this other light hovering.
"We watched it for about 30 seconds before we thought we would record it.
"We thought it was too dark to be a remote helicopter and then it started to move backwards which was a little strange."
What do you think this was? Could it have been a UFO?
