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
Length of current 320 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 next lunation 321 length.
Lunation length longer than mean
Length of current synodic month is 6 hours and 12 minutes longer than the mean length of synodic month, but it is still 51 minutes shorter, compared to 21st century longest.
Lunar orbit position on
True anomaly ∠181.4°
This lunation true anomaly is ∠181.4°. At the beginning of next synodic month true anomaly will be ∠207°. The length of upcoming synodic months will keep decreasing since the true anomaly gets closer to the value of New Moon at point of perigee (∠0° or ∠360°).
Moon in perigee
Moon is reaching point of perigee on this date at 11:06, this is 14 days after last apogee on 20 November 2025 at 02:48 in ♏ Scorpio. Lunar orbit is starting to get wider, while the Moon is moving outward the Earth for 12 days ahead, until it will get to the 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 farther than the closest perigee of 21st century.
Moon after ascending node
5 days after its ascending node on 28 November 2025 at 21:33 in ♓ Pisces, the Moon is following the northern part of its orbit for the next 6 days, until it will cross the ecliptic from North to South in descending node on 11 December 2025 at 07:35 in ♍ Virgo.
Draconic month
5 days after beginning of current draconic month in ♓ Pisces, the Moon is moving from the beginning to the first part of it.
Moon before northern standstill
11 days after previous South standstill on 22 November 2025 at 18:12 in ♐ Sagittarius, when Moon has reached southern declination of ∠-28.295°. Next day the lunar orbit moves northward to face North declination of ∠28.263° in the next northern standstill on 5 December 2025 at 21:51 in ♊ Gemini.
Sun-Earth-Moon syzygy
The Moon is in Full Moon geocentric opposition with the Sun on this date and this alignment forms Sun-Earth-Moon syzygy.
