Moon phase and lunation details

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day 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 ♋ Cancer

Moon is passing about ∠7° of ♋ Cancer tropical zodiac sector.

Apparent angular diameter ∠1891"

Lunar disc appears visually 3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1891" and ∠1949".

Cold Moon before 1 day

Next Full Moon is the Wolf Moon of January 2020 after 28 days on 10 January 2020 at 19:21.

Upcoming main Moon phases

Moderate tide

There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.

Lunation 246 / 1199

The Moon is 16 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

8 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 5 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 378 964 km

The Moon is 378 964 km (235 477 mi) away from Earth and getting closer over the next 5 days until the point perigee when Earth-Moon distance is going to be 370 260 km (230 069 mi).

Moon in ascending node

Moon is in ascending node in ♋ Cancer at 14:15 crossing the ecliptic from South to North to meet descending node 13 days later on 26 December 2019 at 13:01 in ♑ Capricorn.

Previous nodeNext node

New draconic month

At 14:15 the Moon completes the previous draconic month and enters the new one.

PreviousNext

Moon at northern standstill

At 20:57 the Moon is meeting its standstill point to reach North declination of ∠23.226°. This is the year's northernmost lunar standstill of 2019. Over the next 13 days the lunar orbit is going to extend southward to face maximum declination of ∠-23.227° at the point of next standstill in ♑ Capricorn on 26 December 2019 at 20:11.

Previous standstillNext standstill

Syzygy in 12 days

In 12 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.
