Waning Gibbous in Libra

Waning Gibbous on . Illuminated surface of the Moon is 69% and getting smaller. Lunar cycle is 20 days old.

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.

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon in ♎ Libra

Moon is passing about ∠12° of ♎ Libra tropical zodiac sector.

6 days after Full Moon

Previous main lunar phase is the Full Moon before 6 days on 17 January 2041 at 07:11.

Wolf Moon before 6 days

Next Full Moon is the Snow Moon of February 2041 after 23 days on 16 February 2041 at 02:21.

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.

Apparent angular diameter ∠1814"

Lunar disc appears visually 7.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1814" and ∠1949".

Lunation 507 / 1460

The Moon is 20 days old and navigating from the middle to the last part of the current synodic month. This is lunation 507 of Meeus index or 1460 from Brown series.

Synodic month length 29.44 days

The length of this lunation is 29 days, 10 hours and 35 minutes and it is 39 minutes longer than the upcoming lunation's length. The lengths of the following synodic months are going to decrease with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).

Lunation length shorter than mean

The length of the current synodic month is 2 hours and 9 minutes shorter than the mean synodic month length. It is 4 hours longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠342.7°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠342.7° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠358.5°.

Moon after apogee

4 days since point of apogee on 18 January 2041 at 23:16 in ♌ Leo the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 8 days until the Moon reaches the point of next perigee on 1 February 2041 at 07:46 in ♒ Aquarius.

Distance to Moon 395 157 km

The Moon is 395 157 km (245 539 mi) away from Earth and getting closer over the next 8 days until the point perigee when Earth-Moon distance is going to be 356 610 km (221 587 mi).

Moon before descending node

11 days after ascending node on 12 January 2041 at 00:01 in ♉ Taurus the Moon is positioned north of the ecliptic over the following 3 days until the lunar crosses the ecliptic again from North to South in descending node on 26 January 2041 at 15:09 in ♏ Scorpio.

Moon before southern standstill

7 days since the last northern standstill on 15 January 2041 at 15:57 in ♋ Cancer when the Moon has reached North declination of ∠26.766° the lunar orbit is extending southward over the next 6 days to face maximum declination of ∠-26.843° at the point of next southern standstill on 29 January 2041 at 22:24 in ♑ Capricorn.

Draconic month

11 days since the beginning of this draconic month in ♉ Taurus the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 8 days

In 8 days on 1 February 2041 at 05:43 in ♒ Aquarius 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.
