The Moon will reach full phase – making it visible for much of the night, lying almost directly opposite the Sun in the sky.
Full Moons are traditionally given names according to the season in which they fall, and this will be the second full moon of summer 2017, traditionally called the Grain Moon.
Over the nights following 7 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 -15°30' in the constellation Capricornus, and so will appear highest in the southern hemisphere. It will be visible from all latitudes north of 64°N. Its distance from the Earth will be 394,000 km.
The exact position of the Moon at the time it reaches full phase will be:
