Last Quarter in Libra

Last Quarter on . The illuminated surface of the moon is 46% and getting smaller. The lunar cycle is 22 days old.

* The exact date and time of this Last Quarter phase is on 26 December 2078 at 01:16 UTC.

Moonrise and moonset

The moon rises at midnight and sets at noon. It is visible to the south in the morning.

Moon phase and lunation details

Moon in ♎ Libra

Moon is passing about ∠10° of ♎ Libra tropical zodiac sector.

Wolf Moon after 21 days

Next Full Moon is the Wolf Moon of January 2079 after 21 days on 17 January 2079 at 11:06.

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 ∠1800"

Lunar disc appears visually 8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1800" and ∠1951".

Lunation 976 / 1929

The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 976 of Meeus index or 1929 from Brown series.

Synodic month length 29.78 days

The length of this lunation is 29 days, 18 hours and 42 minutes and it is 1 hour and 57 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 longer than mean

The length of the current synodic month is 5 hours and 58 minutes longer than the mean synodic month length. It is 1 hour and 5 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠196.6°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠196.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠225.6°.

Moon before apogee

8 days since point of perigee on 17 December 2078 at 21:10 in ♊ Gemini the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 3 days until the Moon reaches the point of next apogee on 30 December 2078 at 02:17 in ♏ Scorpio.

Distance to Moon 398 134 km

The Moon is 398 134 km (247 389 mi) away from Earth and getting further over the next 3 days until the point apogee when Earth-Moon distance is going to be 405 665 km (252 069 mi).

Moon before descending node

10 days after ascending node on 15 December 2078 at 19:09 in ♉ Taurus the Moon is positioned north of the ecliptic over the following 2 days until the lunar crosses the ecliptic again from North to South in descending node on 28 December 2078 at 21:50 in ♏ Scorpio.

Moon after northern standstill

6 days since the last northern standstill on 19 December 2078 at 14:06 in ♊ Gemini when the Moon has reached North declination of ∠27.536° the lunar orbit is extending southward over the next 7 days to face maximum declination of ∠-27.521° at the point of next southern standstill on 2 January 2079 at 17:40 in ♑ Capricorn.

Draconic month

10 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 7 days

In 7 days on 3 January 2079 at 06:50 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.
