Waning Gibbous in Libra

Waning Gibbous on . Illuminated surface of the Moon is 73% 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 ∠14° of ♎ Libra tropical zodiac sector.

5 days after Full Moon

Previous main lunar phase is the Full Moon before 5 days on 25 January 2024 at 17:54.

Wolf Moon before 5 days

Next Full Moon is the Snow Moon of February 2024 after 24 days on 24 February 2024 at 12:30.

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 ∠1781"

Lunar disc appears visually 8.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1781" and ∠1947".

Lunation 297 / 1250

The Moon is 20 days old and navigating from the middle to the last part of the current synodic month. This is lunation 297 of Meeus index or 1250 from Brown series.

Synodic month length 29.46 days

The length of this lunation is 29 days, 11 hours and 2 minutes and it is 1 hour and 1 minute 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 1 hour and 42 minutes shorter than the mean synodic month length. It is 4 hours and 27 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠328°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠328° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠345.9°.

Moon after apogee

2 days since point of apogee on 29 January 2024 at 08:14 in ♍ Virgo the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 10 days until the Moon reaches the point of next perigee on 10 February 2024 at 18:49 in ♒ Aquarius.

Distance to Moon 402 437 km

The Moon is 402 437 km (250 063 mi) away from Earth and getting closer over the next 10 days until the point perigee when Earth-Moon distance is going to be 358 088 km (222 506 mi).

Moon in descending node

Moon is in descending node in ♎ Libra at 20:17 crossing the ecliptic from North to South. Lunar position remains south of if for the upcoming 13 days until Moon's next ascending node later on 13 February 2024 at 17:01 in ♈ Aries.

Moon before southern standstill

8 days since the last northern standstill on 23 January 2024 at 03:44 in ♋ Cancer when the Moon has reached North declination of ∠28.203° the lunar orbit is extending southward over the next 6 days to face maximum declination of ∠-28.304° at the point of next southern standstill on 6 February 2024 at 17:06 in ♐ Sagittarius.

Draconic month

13 days since the beginning of this draconic month in ♈ Aries the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 9 days

In 9 days on 9 February 2024 at 22:59 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.
