Last Quarter in Libra

Last Quarter on . Illuminated surface of the Moon is 48% and getting smaller. Lunar cycle is 22 days old.

* The exact date and time of this Last Quarter phase is on 24 December 2089 at 07:55 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 ∠6° of ♎ Libra tropical zodiac sector.

Wolf Moon after 22 days

Next Full Moon is the Wolf Moon of January 2090 after 22 days on 16 January 2090 at 03:02.

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 ∠1948"

Lunar disc appears visually 0.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1948" and ∠1951".

Lunation 1112 / 2065

The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 1112 of Meeus index or 2065 from Brown series.

Synodic month length 29.7 days

The length of this lunation is 29 days, 16 hours and 45 minutes and it is 1 hour and 52 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 4 hours and 1 minute longer than the mean synodic month length. It is 3 hours and 2 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠99°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠99° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠135.1°.

Moon after perigee

4 days since point of perigee on 19 December 2089 at 22:47 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 11 days until the Moon reaches the point of next apogee on 4 January 2090 at 23:25 in ♒ Aquarius.

Distance to Moon 367 916 km

The Moon is 367 916 km (228 612 mi) away from Earth and getting further over the next 11 days until the point apogee when Earth-Moon distance is going to be 405 730 km (252 109 mi).

Moon in ascending node

Moon is in ascending node in ♎ Libra at 10:45 crossing the ecliptic from South to North. Lunar position remains north of if for the upcoming 14 days until Moon's next descending node later on 7 January 2090 at 17:09 in ♓ Pisces.

Moon before southern standstill

6 days since the last northern standstill on 17 December 2089 at 19:41 in ♊ Gemini when the Moon has reached North declination of ∠18.446° the lunar orbit is extending southward over the next 6 days to face maximum declination of ∠-18.450° at the point of next southern standstill on 30 December 2089 at 21:23 in ♐ Sagittarius.

New draconic month

At 10:45 in the point ot ascending node the Moon is completing the last draconic month and is entering a new one while the lunar orbit is crossing the ecliptic from South to North.

Syzygy in 7 days

In 7 days on 31 December 2089 at 19:57 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.
