Readers have shared their incredible lunar photos after a blue supermoon lit up the sky this week.

The world was able to witness a rare event on Monday night into the early hours of Tuesday as a blue moon and a supermoon happened at the same time.

During a supermoon, the moon appears up to 14 per cent bigger and 30 per cent brighter compared with when it is furthest away.The Moon over Bovingdon on Saturday night.The Moon over Bovingdon on Saturday night. (Image: Deborah Cang)

Meanwhile, a blue moon – where there are two full moons within a calendar month or the third full moon in a season with four –  happens every two or three years.

The two phenomena only happen together around once every 10 years on average, according to Nasa.

Monday’s moon, the only one that technically qualifies as a full blue supermoon, unfortunately disappointed local photographers due to being hidden behind the clouds.

However, Nasa said it expected the moon to appear full to us for around three days and so those who got out on Sunday and Tuesday night were still able to take some stunning pictures.The Moon seen from between Watford Hemel Hempstead on Tuesday.The Moon seen from between Watford Hemel Hempstead on Tuesday night.
