The rare blue supermoon glimmered over London's landmarks, including Tower Bridge and the Shard, marking one of the year's biggest and brightest moon events.
A blue moon refers to the timing of full moons in a particular year, rather than the actual color of the moon itself, which can appear red.
Supermoons occur when the moon is closest to Earth, appearing up to 14% larger and 30% brighter than when it's at its furthest distance.
The term 'supermoon' was coined by astrologer Richard Nolle in 1979, referring to a new or full moon at 90% of its closest approach to Earth.
