Waning Crescent in Libra

Waning Crescent on . Illuminated surface of the Moon is 25% and getting smaller. Lunar cycle is 24 days old.

Moonrise and moonset

Moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon in ♎ Libra

Moon is passing about ∠16° of ♎ Libra tropical zodiac sector.

2 days after Last Quarter

Previous main lunar phase is the Last Quarter before 2 days on 5 December 2099 at 04:46.

Cold Moon after 20 days

Next Full Moon is the Cold Moon of December 2099 after 20 days on 27 December 2099 at 12:58.

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 ∠1972"

Lunar disc appears visually 1.2% wider than solar disc. Moon and Sun apparent angular diameters are ∠1972" and ∠1948".

Lunation 1235 / 2188

The Moon is 24 days old and navigating from the second to the final part of the current synodic month. This is lunation 1235 of Meeus index or 2188 from Brown series.

Synodic month length 29.49 days

The length of this lunation is 29 days, 11 hours and 40 minutes and it is 2 hours and 7 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 4 minutes shorter than the mean synodic month length. It is 5 hours and 5 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠27.7°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠27.7° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠49.8°.

Moon before perigee

14 days since point of apogee on 22 November 2099 at 17:25 in ♓ Pisces the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next day until the Moon reaches the point of next perigee on 8 December 2099 at 17:50 in ♎ Libra.

Distance to Moon 363 442 km

The Moon is 363 442 km (225 832 mi) away from Earth and getting closer over the next day until the point perigee when Earth-Moon distance is going to be 366 610 km (227 801 mi).

Moon after descending node

1 day after descending node on 5 December 2099 at 21:04 in ♍ Virgo the Moon is positioned south of the ecliptic over the following 11 days until the lunar crosses the ecliptic again from South to North in ascending node on 19 December 2099 at 01:02 in ♓ Pisces.

Moon before southern standstill

7 days since the last northern standstill on 29 November 2099 at 16:41 in ♊ Gemini when the Moon has reached North declination of ∠28.380° the lunar orbit is extending southward over the next 5 days to face maximum declination of ∠-28.351° at the point of next southern standstill on 12 December 2099 at 13:59 in ♐ Sagittarius.

Draconic month

15 days since the beginning of this draconic month in ♓ Pisces the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 4 days

In 4 days on 11 December 2099 at 23:09 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.
