In pictures: The Northern Lights in Scotland
The Northern Lights have again been spotted over parts of Scotland and Northern Ireland overnight.
As we come into the darker months the chances of seeing the Aurora Borealis rise due to the longer periods of darkness and frequent clear nights.
The phenomenon is caused by charged particles from the sun hitting gases in the Earth's atmosphere.
This causes the colourful streaks of light that we are starting to see in Scotland this year.
Here are some of your photographs from across Scotland and Northern Ireland last night.
