Last Quarter in Leo

Last Quarter on . Illuminated surface of the Moon is 58% and getting smaller. Lunar cycle is 21 days old.

* The exact date and time of this Last Quarter phase is on 12 November 2055 at 05:38 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 ♌ Leo

Moon is passing about ∠10° of ♌ Leo tropical zodiac sector.

Cold Moon after 22 days

Next Full Moon is the Cold Moon of December 2055 after 22 days on 4 December 2055 at 05:40.

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 ∠1912"

Lunar disc appears visually 1.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1912" and ∠1938".

Lunation 690 / 1643

The Moon is 21 days old and navigating through the last part of the current synodic month. This is lunation 690 of Meeus index or 1643 from Brown series.

Synodic month length 29.41 days

The length of this lunation is 29 days, 9 hours and 45 minutes and it is 1 hour and 56 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 2 hours and 59 minutes shorter than the mean synodic month length. It is 3 hours and 10 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠7.9°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠7.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠24.3°.

Moon before perigee

9 days since point of apogee on 1 November 2055 at 20:44 in ♈ Aries 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 17 November 2055 at 09:42 in ♏ Scorpio.

Distance to Moon 374 896 km

The Moon is 374 896 km (232 950 mi) away from Earth and getting closer over the next 5 days until the point perigee when Earth-Moon distance is going to be 360 295 km (223 877 mi).

Moon in ascending node

Moon is in ascending node in ♌ Leo at 01:13 crossing the ecliptic from South to North. Lunar position remains north of if for the upcoming 12 days until Moon's next descending node later on 23 November 2055 at 14:19 in ♑ Capricorn.

Moon after northern standstill

2 days since the last northern standstill on 9 November 2055 at 06:27 in ♋ Cancer when the Moon has reached North declination of ∠21.007° the lunar orbit is extending southward over the next 10 days to face maximum declination of ∠-21.087° at the point of next southern standstill on 21 November 2055 at 23:06 in ♑ Capricorn.

New draconic month

At 01:13 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 18 November 2055 at 20:34 in ♏ Scorpio 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.
