Waning Crescent in Libra

Waning Crescent on . The illuminated surface of the moon is 13% and getting smaller. The lunar cycle is 26 days old.

Moonrise and moonset

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

Moon phase and lunation details

Moon in ♎ Libra

Moon is passing about ∠25° of ♎ Libra tropical zodiac sector.

4 days after Last Quarter

Previous main lunar phase is the Last Quarter before 4 days on 25 November 2051 at 04:02.

Cold Moon after 18 days

Next Full Moon is the Cold Moon of December 2051 after 18 days on 17 December 2051 at 16:05.

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 ∠1769"

Lunar disc appears visually 9.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1769" and ∠1945".

Lunation 641 / 1594

The Moon is 26 days old and navigating from the second to the final part of the current synodic month. This is lunation 641 of Meeus index or 1594 from Brown series.

Synodic month length 29.78 days

The length of this lunation is 29 days, 18 hours and 38 minutes and it is 1 hour and 9 minutes longer than the upcoming lunation's length. This is the year's longest synodic month of 2051. The lengths of the following synodic months are going to decrease with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).

Lunation length longer than mean

The length of the current synodic month is 5 hours and 54 minutes longer than the mean synodic month length. It is 1 hour and 9 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠187.8°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠187.8° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠214.3°.

Moon at apogee

Moon is at apogee at 23:42 about 12 days since last perigee on 17 November 2051 at 10:55 in ♉ Taurus the lunar orbit is going to narrow while the Moon is moving towards the Earth over the upcoming 16 days until point of next perigee on 15 December 2051 at 19:57 in ♉ Taurus.

Distance to Moon 405 942 km

This apogee Moon is 405 942 km (252 241 mi) away from Earth. It is 534 km further than the mean apogee distance, but it is still 767 km closer than the farthest apogee of 21st century.

Moon in ascending node

Moon is in ascending node in ♎ Libra at 08:08 crossing the ecliptic from South to North. Lunar position remains north of if for the upcoming 13 days until Moon's next descending node later on 13 December 2051 at 08:09 in ♈ Aries.

Moon before southern standstill

9 days since the last northern standstill on 20 November 2051 at 02:16 in ♊ Gemini when the Moon has reached North declination of ∠18.736° the lunar orbit is extending southward over the next 4 days to face maximum declination of ∠-18.781° at the point of next southern standstill on 4 December 2051 at 11:27 in ♐ Sagittarius.

New draconic month

At 08:08 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 3 days

In 3 days on 3 December 2051 at 09:37 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.
