Stargazers and lunatics alike have a treat in store for them this weekend, when a "supermoon" will appear in the skies on Sunday 6 May.
The full moon on 6 May is the closest and largest full moon of this year. Called a perigee full moon, it will be at the closest possible point to the Earth, making it appear much larger than usual.
A supermoon is also simply a delight to behold. The supermoon in May is 14% bigger and 30% brighter than other full moons, according to Nasa, making 6 May a great time for a night walk.
While a 16% increase is very hard to measure, the moon will appear larger and brighter for the night of 6 May in the UK and 5 May in the US.
The perigee moon appears each month, but a magnificent supermoon last appeared on 19 March 2011, looming over London and glowing a deep, dark orange.
