Overview

• The full phase occurs at 4:48 a.m. BST on 7 October, making it the year’s largest and brightest full moon.
• In the UK it rises around 6:20 p.m. on Tuesday and will be visible for several evenings around sunset.
• Forecasters expect clearer skies for much of southern England and Wales, with greater cloud and rain risk in northern areas after Storm Amy.
• The event meets the common supermoon definition of a full moon within 90% of perigee, though some stricter criteria would not classify it as such.
• NASA notes that the apparent size near the horizon is a perception effect, and additional supermoons are due in November and December.
