The Moon will reach full phase. At this time of the month, the Moon is visible for much of the night, rising at around dusk, and setting at around dawn.
Over the nights following 18 December, 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 in the middle of the night and set at around noon.
At the moment when the Moon reaches full phase, it will lie at a declination of +25°41' in the constellation Taurus . Its distance from the Earth will be 405,000 km.
The celestial coordinates of the Moon at the time it reaches full phase will be:
| Object | Right Ascension | Declination | Constellation | Angular Size |
| The Moon | 05h47m30s | +25°41' | Taurus | 29'25" |
The coordinates above are given in J2000.0.
