A Scottish loch glowed bright green as the Northern Lights were seen in the UK for the first time this year.
The stunning images were captured by photographer Maciej Winiarczyk, who is based in Wick, Caithness, on the far north of mainland Scotland.
The talented snapper was able to capture the pictures on Thursday night because of the darker nights.
The Northern and Southern Lights are natural light spectacles triggered in our atmosphere that are all known as the "Auroras".
One of the images was taken at Sinclair's Bay in Caithness and the other was taken at Loch Watten.
There are two types of Aurora - Aurora Borealis, which means "dawn of the North" and Aurora Australis which means "dawn of the South".
The green colour is caused by collisions with oxygen particles but different atmospheric gases can produce a blue, violet, yellow or even red colour.
These reactions occur at magnetic poles which is why auroras are more likely to be spotted in Scotland and northern parts of the country.
On Thursday evening Aurora Watch UK, a free service run by scientists which offers alerts of when aurora might be visible in the UK, tweeted about possible aurora sightings in the north if conditions were right.
The tweet read: "A G1 (minor) geomagnetic storm watch for 24-25 October has been issued by NOAA Space Weather due to the recurrence of a coronal hole high speed stream (fast solar wind).
"This could mean #aurora sightings from the UK, particularly in the north, assuming conditions are right."
