Moon phase and lunation details
Moonrise and moonset
Moon rises at sunset and sets at sunrise. It is visible all night and it is high in the sky around midnight.
Moon in ♊ Gemini
Moon is passing about ∠6° of ♊ Gemini tropical zodiac sector.
Apparent angular diameter ∠1972"
Lunar disc appears visually 1.3% wider than solar disc. Moon and Sun apparent angular diameters are ∠1972" and ∠1947".
It is Cold Moon
The Full Moon this days is the Cold of December 2025.
Upcoming main Moon phases
- Last Quarter in Virgo ♍ on 11 December 2025 at 20:52
- New Moon in Sagittarius ♐ on 20 December 2025 at 01:43
- First Quarter in Pisces ♓ on 27 December 2025 at 19:10

Spring tide
There is high Full Moon ocean tide on this date. Combined Sun and Moon gravitational tidal force working on Earth is strong, because of the Sun-Earth-Moon syzygy alignment.
Lunation 320 / 1273
The Moon is 14 days old. Earth's natural satellite is moving through the middle part of current synodic month. This is lunation 320 of Meeus index or 1273 from Brown series.
Synodic month length 29.79 days
The length of the lunation is 29 days, 18 hours and 56 minutes. This is the year's longest synodic month of 2025. It is 47 minutes longer than the next lunation's length. The lengths of the following synodic months are going to decreasing with the true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).
Lunation length longer than mean
The length of the current synodic month is 6 hours and 12 minutes longer than the mean synodic month length. It is 51 minutes shorter compared to 21st century's longest synodic month length.
Lunar orbit position on
True anomaly ∠181.4°
At the beginning of the lunation cycle the true anomaly is ∠181.4°. At the beginning of next synodic month the true anomaly is going to be ∠207°.
Moon at perigee
Moon is at perigee at 11:06. It is 14 days after previous apogee on 20 November 2025 at 02:48 in ♏ Scorpio. Lunar orbit is going to widen while the Moon is moving away from the Earth over the next 12 days, until point of next apogee on 17 December 2025 at 06:09 in ♏ Scorpio.
Distance to Moon 356 962 km
This perigee Moon is 356 962 km (221 806 mi) away from Earth. It is 5 546 km closer than the mean perigee distance, but it is still 13 394 km further than the closest perigee of 21st century.
Moon after ascending node
5 days after ascending node on 28 November 2025 at 21:33 in ♓ Pisces. The Moon is located north of the ecliptic over the following 6 days, until the lunar orbit crosses from North to South in descending node on 11 December 2025 at 07:35 in ♍ Virgo.
Draconic month
5 days since the beginning of current draconic month in ♓ Pisces, the Moon is navigating from the beginning to the first part of the cycle.
Moon before northern standstill
11 days since the previous standstill on 22 November 2025 at 18:12 in ♐ Sagittarius when the Moon has reached South declination of ∠-28.295°, the lunar orbit is extending northward over the next day to face maximum declination of ∠28.263° at the point of next northern standstill on 5 December 2025 at 21:51 in ♊ Gemini.
Sun-Earth-Moon syzygy
The Moon is in a Full Moon geocentric opposition with the Sun and thus forming Sun-Earth-Moon syzygy alignment.
