The Moon will reach full phase – making it visible for much of the night, lying almost directly opposite the Sun in the sky.
This full moon will take place unusually close to the time of month when the Moon makes its closest approach to the Earth – called its perigee. This near coincidence between a full moon and lunar perigee will mean that this full moon will appear slightly larger and brighter than usual in the night sky. Full moons such as this are sometimes called supermoons, and occur roughly once every 13 months.
Full Moons are traditionally given names according to the season in which they fall, and this will be the third full moon of summer 2015, traditionally called the Fruit Moon.
Over the nights following 29 August, the Moon will rise around an hour later each day so as to become prominent later in the night. Within a few days, it will only be visible in the pre-dawn and early-morning sky. By the time it reaches last quarter, a week after full moon, it will rise at around midnight and set at around noon.
At the moment when the Moon reaches full phase, it will lie at a declination of -07°16' in the constellation Aquarius, and so will appear high in the sky at all but the most extreme latitudes. It will be visible at all latitudes between 72°N and 87°S. Its distance from the Earth will be 358,000 km.
The exact position of the Moon at the time it reaches full phase will be:
