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 6 January 2021 at 09:37 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 ∠18° of ♎ Libra tropical zodiac sector.

Wolf Moon after 22 days

Next Full Moon is the Wolf Moon of January 2021 after 22 days on 28 January 2021 at 19:16.

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 ∠1966"

Lunar disc appears visually 0.8% wider than solar disc. Moon and Sun apparent angular diameters are ∠1966" and ∠1951".

Lunation 259 / 1212

The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 259 of Meeus index or 1212 from Brown series.

Synodic month length 29.53 days

The length of this lunation is 29 days, 12 hours and 44 minutes and it is 1 hour and 21 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 same as the mean

The length of the current synodic month is equal to the mean synodic month length. It is %hours_to_shortest% and %minutes_to_shortest% longer than the 21st century's shortest and %hours_to_longest% and %minutes_to_longest% shorter than the 21st century's longest synodic months.

Lunar orbit details for

True anomaly ∠30.1°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠30.1° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠53.8°.

Moon before perigee

12 days since point of apogee on 24 December 2020 at 16:32 in ♈ Aries the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 3 days until the Moon reaches the point of next perigee on 9 January 2021 at 15:39 in ♏ Scorpio.

Distance to Moon 364 531 km

The Moon is 364 531 km (226 509 mi) away from Earth and getting closer over the next 3 days until the point perigee when Earth-Moon distance is going to be 367 390 km (228 286 mi).

Moon before descending node

8 days after ascending node on 28 December 2020 at 15:03 in ♊ Gemini the Moon is positioned north of the ecliptic over the following 4 days until the lunar crosses the ecliptic again from North to South in descending node on 10 January 2021 at 20:15 in ♐ Sagittarius.

Moon before southern standstill

7 days since the last northern standstill on 30 December 2020 at 07:53 in ♋ Cancer when the Moon has reached North declination of ∠24.868° the lunar orbit is extending southward over the next 5 days to face maximum declination of ∠-24.870° at the point of next southern standstill on 12 January 2021 at 08:18 in ♑ Capricorn.

Draconic month

8 days since the beginning of this draconic month in ♊ Gemini the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 6 days

In 6 days on 13 January 2021 at 05:00 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.
