The Moon will pass last quarter phase, rising in the middle of the night and appearing prominent in the pre-dawn sky.
From Fairfield, it will be visible from soon after it rises, at 02:41, until soon before it sets at 11:05.
At this time in its monthly cycle of phases, it appears almost exactly half illuminated.
The Moon orbits the Earth once every four weeks, causing its phases to cycle through new moon, first quarter, full moon, last quarter, and back to new moon once every 29.5 days.
As it progresses through this cycle, it is visible at different times of day. At last quarter, it rises in the middle of the night and appears high in the sky by dawn. It sets at around lunchtime. More information about the Moon's phases is available here.
Observing the Moon at last quarter
Over coming days, the Moon will rise later each day, so that it is visible for less time before sunrise and rises less far above the eastern horizon before dawn. By the time it reaches new moon, it will rise at around dawn and set at around dusk, making it visible only during the daytime.
Its daily progress is charted below, with all times are given in Fairfield local time.

The exact moment of last quarter
The exact moment of last quarter is defined as the time when the Moon's ecliptic longitude is exactly 90° away from the Sun's ecliptic longitude, as observed from the center of the Earth. However, the Moon does not appear in any way special at this instant in time, and a last quarter moon can be observed at any time in the pre-dawn sky.
At the moment it reaches last quarter, the Moon's distance from the Earth will be 403,000 km. Its celestial coordinates will be as follows:
| Object | Right Ascension | Declination | Constellation | Angular Size |
| The Moon | 17h16m40s | 28°14'S | Ophiuchus | 29'34" |
The coordinates above are given in J2000.0.
