The Moon will reach full phase. At this time in its monthly cycle of phases, the Moon lies almost directly opposite the Sun in the sky, placing it high above the horizon for much of the night.

The sequence of full moons through the year are often assigned names according to the seasons in which they fall. This month's will be the second to fall in summer 2025 – the Grain Moon.

Over the nights following 9 August, the Moon will rise around an hour later each day, becoming 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 exact moment when the Moon reaches full phase, it will lie at a declination of -18°26' in the constellation Capricornus , and so will appear highest in the southern hemisphere. It will be visible from all latitudes north of 61°N. Its distance from the Earth will be 380,000 km.

The exact position of the Moon at the time it reaches full phase will be:

Object Right Ascension Declination Constellation Angular Size
The Moon 21h19m50s -18°26' Capricornus 31'25"

The coordinates above are given in J2000.0.
