Moon phase and lunation details

3 days after Last Quarter

Previous main lunar phase is the Last Quarter before 3 days on 18 December 2030 at 00:01.

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 ∠14° of ♏ Scorpio tropical zodiac sector.

Apparent angular diameter ∠1951"

Lunar disc appears visually 0% wider than solar disc. Moon and Sun apparent angular diameters are ∠1951" and ∠1951".

Wolf Moon after 18 days

Next Full Moon is the Wolf Moon of January 2031 after 18 days on 8 January 2031 at 18:26.

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 382 / 1335

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 382 of Meeus index or 1335 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.45 days

The length of the lunation is 29 days, 10 hours and 46 minutes. It is 13 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 58 minutes shorter than the mean synodic month length. It is 4 hours and 11 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠349.8°

At the beginning of the lunation cycle the true anomaly is ∠349.8°. At the beginning of next synodic month the true anomaly is going to be ∠5.3°.

Moon before apogee

11 days after point of apogee on 10 December 2030 at 10:03 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 24 December 2030 at 10:09 in ♐ Sagittarius.

Previous apogeeNext perigee

Distance to Moon 367 395 km

The Moon is 367 395 km (228 289 mi) away from Earth and getting closer over the next 2 days until the point perigee when Earth-Moon distance is going to be 356 926 km (221 784 mi).

Moon before ascending node

12 days after descending node on 9 December 2030 at 01:17 in ♊ Gemini. The Moon is located south of the ecliptic over the following day, until the lunar orbit crosses from South to North in ascending node on 23 December 2030 at 00:54 in ♐ Sagittarius.

Draconic month

25 days since the beginning of current draconic month in ♏ Scorpio, the Moon is navigating from the second to the final part of the cycle.

Moon before southern standstill

11 days since the previous standstill on 9 December 2030 at 22:37 in ♊ Gemini when the Moon has reached North declination of ∠21.909°, the lunar orbit is extending southward over the next 2 days to face maximum declination of ∠-21.904° at the point of next southern standstill on 23 December 2030 at 18:07 in ♐ Sagittarius.

Syzygy in 3 days

In 3 days on 24 December 2030 at 17:32 in ♐ Sagittarius 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.
