Moon phase and lunation details

3 days after Full Moon

Previous main lunar phase is the Full Moon before 3 days on 14 December 2073 at 13:49.

Moonrise and moonset

Moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.

Moon in ♌ Leo

Moon is passing about ∠13° of ♌ Leo tropical zodiac sector.

Apparent angular diameter ∠1888"

Lunar disc appears visually 3.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1888" and ∠1950".

Cold Moon before 3 days

Next Full Moon is the Wolf Moon of January 2074 after 25 days on 13 January 2074 at 06:31.

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 914 / 1867

The Moon is 18 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 914 of Meeus index or 1867 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.49 days

The length of the lunation is 29 days, 11 hours and 43 minutes. It is 1 hour and 59 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 1 minute shorter than the mean synodic month length. It is 5 hours and 8 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠22.5°

At the beginning of the lunation cycle the true anomaly is ∠22.5°. At the beginning of next synodic month the true anomaly is going to be ∠43.1°.

Moon before apogee

8 days after point of apogee on 9 December 2073 at 22:16 in ♈ Aries. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 7 days, until the Moon reaches the point of next perigee on 25 December 2073 at 23:45 in ♏ Scorpio.

Previous apogeeNext perigee

Distance to Moon 379 662 km

The Moon is 379 662 km (235 911 mi) away from Earth and getting closer over the next 7 days until the point perigee when Earth-Moon distance is going to be 365 051 km (226 832 mi).

Moon in ascending node

Moon is in ascending node in ♌ Leo at 11:14 crossing the ecliptic from South to North to meet descending node 12 days later on 31 December 2073 at 05:26 in ♒ Aquarius.

Previous nodeNext node

New draconic month

At 11:14 the Moon completes the previous draconic month and enters the new one.

Moon after northern standstill

2 days since the previous standstill on 15 December 2073 at 22:12 in ♋ Cancer when the Moon has reached North declination of ∠20.261°, the lunar orbit is extending southward over the next 10 days to face maximum declination of ∠-20.262° at the point of next southern standstill on 28 December 2073 at 21:38 in ♑ Capricorn.

Previous standstillNext standstill

Syzygy in 10 days

In 10 days on 28 December 2073 at 16:55 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.
