A rare blue supermoon illuminated the skies in London last night to the delight of stargazers.
A ‘blue’ moon refers to the second full moon in one calendar month, which occurs approximately once every two or three years, rather than its colour.
It was unusually close to Earth on Wednesday night, therefore a ‘supermoon’.
The lunar phenomenon, which last occurred in 2009, drew Londoners out of their homes in their droves to take photographs.
The next blue moons will occur in a pair in January and March 2037, so the saying "once in a blue moon" rings true.
Londoners took to social media to share photos of the spectacle. From Hampstead Heath to Tower Bridge, we’ve rounded up some snaps of the blue supermoon seen from London.
