Waning Gibbous in Libra

Waning Gibbous on . The illuminated surface of the moon is 65% and getting smaller. The lunar cycle is 20 days old.

Moonrise and moonset

The 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 phase and lunation details

Moon in ♎ Libra

Moon is passing about ∠5° of ♎ Libra tropical zodiac sector.

5 days after Full Moon

Previous main lunar phase is the Full Moon before 5 days on 7 January 2080 at 01:45.

Wolf Moon before 5 days

Next Full Moon is the Snow Moon of February 2080 after 24 days on 5 February 2080 at 12:21.

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 ∠1880"

Lunar disc appears visually 3.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1880" and ∠1951".

Lunation 989 / 1942

The Moon is 20 days old and navigating from the middle to the last part of the current synodic month. This is lunation 989 of Meeus index or 1942 from Brown series.

Synodic month length 29.81 days

The length of this lunation is 29 days, 19 hours and 24 minutes and it is 1 hour and 8 minutes longer than the upcoming lunation's length. This is the year's longest synodic month of 2080. 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 longer than mean

The length of the current synodic month is 6 hours and 40 minutes longer than the mean synodic month length. It is 23 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠174.6°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠174.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠199.5°.

Moon after perigee

5 days since point of perigee on 6 January 2080 at 19:49 in ♋ Cancer the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 7 days until the Moon reaches the point of next apogee on 19 January 2080 at 22:45 in ♑ Capricorn.

Distance to Moon 381 362 km

The Moon is 381 362 km (236 967 mi) away from Earth and getting further over the next 7 days until the point apogee when Earth-Moon distance is going to be 406 533 km (252 608 mi).

Moon before descending node

11 days after ascending node on 31 December 2079 at 23:44 in ♈ Aries the Moon is positioned north of the ecliptic over the following day until the lunar crosses the ecliptic again from North to South in descending node on 13 January 2080 at 09:00 in ♎ Libra.

Moon after northern standstill

6 days since the last northern standstill on 6 January 2080 at 04:42 in ♋ Cancer when the Moon has reached North declination of ∠28.224° the lunar orbit is extending southward over the next 7 days to face maximum declination of ∠-28.251° at the point of next southern standstill on 19 January 2080 at 15:20 in ♐ Sagittarius.

Draconic month

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

Syzygy in 9 days

In 9 days on 22 January 2080 at 01:55 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.
