Last Quarter in Libra

Last Quarter on . Illuminated surface of the Moon is 49% and getting smaller. Lunar cycle is 22 days old.

* The exact date and time of this Last Quarter phase is on 12 January 2072 at 09:54 UTC.

Moonrise and moonset

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

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon in ♎ Libra

Moon is passing about ∠23° of ♎ Libra tropical zodiac sector.

Snow Moon after 22 days

Next Full Moon is the Snow Moon of February 2072 after 22 days on 4 February 2072 at 04:55.

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 ∠1908"

Lunar disc appears visually 2.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1908" and ∠1951".

Lunation 890 / 1843

The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 890 of Meeus index or 1843 from Brown series.

Synodic month length 29.78 days

The length of this lunation is 29 days, 18 hours and 48 minutes and it is 41 minutes shorter than the upcoming lunation's length. The lengths of the following synodic months are going to increase with the lunar orbit 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 6 hours and 4 minutes longer than the mean synodic month length. It is 59 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠138.1°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠138.1° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠166.3°.

Moon after perigee

5 days since point of perigee on 6 January 2072 at 17:46 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 9 days until the Moon reaches the point of next apogee on 21 January 2072 at 20:00 in ♒ Aquarius.

Distance to Moon 375 711 km

The Moon is 375 711 km (233 456 mi) away from Earth and getting further over the next 9 days until the point apogee when Earth-Moon distance is going to be 406 490 km (252 581 mi).

Moon after ascending node

2 days after ascending node on 10 January 2072 at 03:26 in ♍ Virgo the Moon is positioned north of the ecliptic over the following 11 days until the lunar crosses the ecliptic again from North to South in descending node on 24 January 2072 at 10:50 in ♓ Pisces.

Moon before southern standstill

7 days since the last northern standstill on 4 January 2072 at 21:58 in ♊ Gemini when the Moon has reached North declination of ∠18.460° the lunar orbit is extending southward over the next 5 days to face maximum declination of ∠-18.436° at the point of next southern standstill on 18 January 2072 at 00:05 in ♑ Capricorn.

Draconic month

2 days since the beginning of this draconic month in ♍ Virgo the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 7 days

In 7 days on 20 January 2072 at 06:35 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.
