Moon phase and lunation details

3 days after Last Quarter

Previous main lunar phase is the Last Quarter before 3 days on 27 December 2021 at 02:24.

Moonrise and moonset

Moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.

Moon in ♏ Scorpio

Moon is passing about ∠23° of ♏ Scorpio tropical zodiac sector.

Apparent angular diameter ∠1964"

Lunar disc appears visually 0.6% wider than solar disc. Moon and Sun apparent angular diameters are ∠1964" and ∠1951".

Wolf Moon after 18 days

Next Full Moon is the Wolf Moon of January 2022 after 18 days on 17 January 2022 at 23:49.

Upcoming main Moon phases

Neap tide

There is low ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at big angle, so their combined tidal force is weak.

Lunation 271 / 1224

The Moon is 25 days old. Earth's natural satellite is moving from the second to the final part of current synodic month. This is lunation 271 of Meeus index or 1224 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.45 days

The length of the lunation is 29 days, 10 hours and 50 minutes. It is 23 minutes shorter than the next lunation's length. The lengths of the following synodic months are going to increasing with the true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).

Lunation length shorter than mean

The length of the current synodic month is 1 hour and 54 minutes shorter than the mean synodic month length. It is 4 hours and 15 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠358.3°

At the beginning of the lunation cycle the true anomaly is ∠358.3°. At the beginning of next synodic month the true anomaly is going to be ∠13.9°.

Moon before apogee

12 days after point of apogee on 18 December 2021 at 02:16 in ♊ Gemini. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 2 days, until the Moon reaches the point of next perigee on 1 January 2022 at 23:00 in ♐ Sagittarius.

Previous apogeeNext perigee

Distance to Moon 364 985 km

The Moon is 364 985 km (226 791 mi) away from Earth and getting closer over the next 2 days until the point perigee when Earth-Moon distance is going to be 358 037 km (222 474 mi).

Moon before descending node

13 days after ascending node on 17 December 2021 at 00:12 in ♊ Gemini. The Moon is located north of the ecliptic over the following day, until the lunar orbit crosses from North to South in descending node on 31 December 2021 at 01:07 in ♐ Sagittarius.

Draconic month

13 days since the beginning of current draconic month in ♊ Gemini, the Moon is navigating from the beginning to the first part of the cycle.

Moon before southern standstill

10 days since the previous standstill on 20 December 2021 at 04:32 in ♋ Cancer when the Moon has reached North declination of ∠26.306°, the lunar orbit is extending southward over the next 3 days to face maximum declination of ∠-26.304° at the point of next southern standstill on 2 January 2022 at 13:35 in ♑ Capricorn.

Syzygy in 3 days

In 3 days on 2 January 2022 at 18:33 in ♑ Capricorn the Moon is going to be in a New Moon geocentric conjunction with the Sun and thus forming the next Sun-Moon-Earth syzygy alignment.
