Waning Gibbous in Leo

Waning Gibbous on . Illuminated surface of the Moon is 82% and getting smaller. Lunar cycle is 19 days old.

Moonrise and moonset

Moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon in ♌ Leo

Moon is passing about ∠7° of ♌ Leo tropical zodiac sector.

4 days after Full Moon

Previous main lunar phase is the Full Moon before 4 days on 4 December 2055 at 05:40.

Cold Moon before 4 days

Next Full Moon is the Wolf Moon of January 2056 after 25 days on 2 January 2056 at 22:05.

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 ∠1901"

Lunar disc appears visually 2.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1901" and ∠1948".

Lunation 691 / 1644

The Moon is 19 days old and navigating from the middle to the last part of the current synodic month. This is lunation 691 of Meeus index or 1644 from Brown series.

Synodic month length 29.49 days

The length of this lunation is 29 days, 11 hours and 41 minutes and it is 2 hours and 14 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 3 minutes shorter than the mean synodic month length. It is 5 hours and 6 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠24.3°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠24.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠45.5°.

Moon before perigee

9 days since point of apogee on 29 November 2055 at 09:39 in ♈ Aries the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 6 days until the Moon reaches the point of next perigee on 15 December 2055 at 10:52 in ♏ Scorpio.

Distance to Moon 377 107 km

The Moon is 377 107 km (234 323 mi) away from Earth and getting closer over the next 6 days until the point perigee when Earth-Moon distance is going to be 365 611 km (227 180 mi).

Moon in ascending node

Moon is in ascending node in ♌ Leo at 02:26 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 20 December 2055 at 21:00 in ♑ Capricorn.

Moon after northern standstill

1 day since the last northern standstill on 6 December 2055 at 12:59 in ♋ Cancer when the Moon has reached North declination of ∠21.161° the lunar orbit is extending southward over the next 10 days to face maximum declination of ∠-21.183° at the point of next southern standstill on 19 December 2055 at 10:14 in ♑ Capricorn.

New draconic month

At 02:26 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 9 days

In 9 days on 18 December 2055 at 08:15 in ♐ Sagittarius 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.
