Waning Crescent in Libra

Waning Crescent on . Illuminated surface of the Moon is 37% and getting smaller. Lunar cycle is 23 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 is entering ♎ Libra

Moon is passing first ∠1° of ♎ Libra tropical zodiac sector.

1 day after Last Quarter

Previous main lunar phase is the Last Quarter before 1 day on 5 December 2088 at 04:58.

Cold Moon after 21 days

Next Full Moon is the Cold Moon of December 2088 after 21 days on 28 December 2088 at 00:57.

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 ∠1889"

Lunar disc appears visually 3.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1889" and ∠1948".

Lunation 1099 / 2052

The Moon is 23 days old and navigating from the second to the final part of the current synodic month. This is lunation 1099 of Meeus index or 2052 from Brown series.

Synodic month length 29.76 days

The length of this lunation is 29 days, 18 hours and 20 minutes and it is 1 hour and 6 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 longer than mean

The length of the current synodic month is 5 hours and 36 minutes longer than the mean synodic month length. It is 1 hour and 27 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠131.6°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠131.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠160.8°.

Moon after perigee

6 days since point of perigee on 29 November 2088 at 18:53 in ♊ Gemini the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 8 days until the Moon reaches the point of next apogee on 15 December 2088 at 03:25 in ♑ Capricorn.

Distance to Moon 379 396 km

The Moon is 379 396 km (235 746 mi) away from Earth and getting further over the next 8 days until the point apogee when Earth-Moon distance is going to be 406 541 km (252 613 mi).

Moon before ascending node

10 days after descending node on 25 November 2088 at 20:19 in ♈ Aries the Moon is positioned south of the ecliptic over the following day until the lunar crosses the ecliptic again from South to North in ascending node on 8 December 2088 at 11:52 in ♎ Libra.

Moon before southern standstill

6 days since the last northern standstill on 29 November 2088 at 15:58 in ♊ Gemini when the Moon has reached North declination of ∠18.926° the lunar orbit is extending southward over the next 6 days to face maximum declination of ∠-18.960° at the point of next southern standstill on 13 December 2088 at 04:28 in ♐ Sagittarius.

Draconic month

25 days since the beginning of this draconic month in ♎ Libra the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 6 days

In 6 days on 13 December 2088 at 00:52 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.
