If you were looking up at the skies during the early hours this morning, you might have noticed the moon wasn't looking like its normal self.
As a result of a rare celestial event where a supermoon - that's when the moon is at the closest point to the Earth and appears larger - coincided with a lunar eclipse, the moon looked red in the sky.
For those who weren't up and about during the event, here's just a few pictures from the intrepid Glasgow social media users who pulled an all-nighter.
