Moon phase and lunation details

4 days after Full Moon

Previous main lunar phase is the Full Moon before 4 days on 12 December 2019 at 05:12.

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 ∠19° of ♌ Leo tropical zodiac sector.

Apparent angular diameter ∠1952"

Lunar disc appears visually 0.1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1952" and ∠1950".

Cold Moon before 4 days

Next Full Moon is the Wolf Moon of January 2020 after 25 days on 10 January 2020 at 19:21.

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 246 / 1199

The Moon is 19 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 246 of Meeus index or 1199 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.59 days

The length of the lunation is 29 days, 14 hours and 8 minutes. It is 2 hours and 21 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 longer than mean

The length of the current synodic month is 1 hour and 23 minutes longer than the mean synodic month length. It is 5 hours and 39 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit position on

True anomaly ∠50.7°

At the beginning of the lunation cycle the true anomaly is ∠50.7°. At the beginning of next synodic month the true anomaly is going to be ∠82.6°.

Moon before apogee

11 days after point of apogee on 5 December 2019 at 04:09 in ♓ Pisces. 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 18 December 2019 at 20:30 in ♍ Virgo.

Previous apogeeNext perigee

Distance to Moon 367 131 km

The Moon is 367 131 km (228 125 mi) away from Earth and getting closer over the next 2 days until the point perigee when Earth-Moon distance is going to be 370 260 km (230 069 mi).

Moon after ascending node

2 days after ascending node on 13 December 2019 at 14:15 in ♋ Cancer. The Moon is located north of the ecliptic over the following 10 days, until the lunar orbit crosses from North to South in descending node on 26 December 2019 at 13:01 in ♑ Capricorn.

Draconic month

2 days since the beginning of current draconic month in ♋ Cancer, the Moon is navigating from the beginning to the first part of the cycle.

Moon after northern standstill

2 days since the previous standstill on 13 December 2019 at 20:57 in ♋ Cancer when the Moon has reached North declination of ∠23.226°, the lunar orbit is extending southward over the next 10 days to face maximum declination of ∠-23.227° at the point of next southern standstill on 26 December 2019 at 20:11 in ♑ Capricorn.

Syzygy in 9 days

In 9 days on 26 December 2019 at 05:13 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.
