Last Quarter in Libra

Last Quarter on . The illuminated surface of the moon is 57% and getting smaller. The lunar cycle is 21 days old.

* The exact date and time of this Last Quarter phase is on 10 January 2075 at 03:14 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 ∠11° of ♎ Libra tropical zodiac sector.

Snow Moon after 22 days

Next Full Moon is the Snow Moon of February 2075 after 22 days on 1 February 2075 at 04:13.

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 ∠1914"

Lunar disc appears visually 1.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1914" and ∠1951".

Lunation 927 / 1880

The Moon is 21 days old and navigating through the last part of the current synodic month. This is lunation 927 of Meeus index or 1880 from Brown series.

Synodic month length 29.47 days

The length of this lunation is 29 days, 11 hours and 17 minutes and it is 47 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 shorter than mean

The length of the current synodic month is 1 hour and 27 minutes shorter than the mean synodic month length. It is 4 hours and 42 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠7.7°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠7.7° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠24.6°.

Moon before perigee

9 days since point of apogee on 30 December 2074 at 16:12 in ♊ Gemini the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 5 days until the Moon reaches the point of next perigee on 15 January 2075 at 07:21 in ♑ Capricorn.

Distance to Moon 374 434 km

The Moon is 374 434 km (232 663 mi) away from Earth and getting closer over the next 5 days until the point perigee when Earth-Moon distance is going to be 360 371 km (223 924 mi).

Moon after ascending node

6 days after ascending node on 3 January 2075 at 08:42 in ♋ Cancer the Moon is positioned north of the ecliptic over the following 7 days until the lunar crosses the ecliptic again from North to South in descending node on 16 January 2075 at 13:41 in ♑ Capricorn.

Moon before southern standstill

7 days since the last northern standstill on 2 January 2075 at 09:48 in ♋ Cancer when the Moon has reached North declination of ∠21.829° the lunar orbit is extending southward over the next 6 days to face maximum declination of ∠-21.820° at the point of next southern standstill on 15 January 2075 at 19:15 in ♑ Capricorn.

Draconic month

6 days since the beginning of this draconic month in ♋ Cancer the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 7 days

In 7 days on 16 January 2075 at 18:37 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.
