Waning Gibbous in Libra

Waning Gibbous on . The illuminated surface of the moon is 79% and getting smaller. The lunar cycle is 19 days old.

Moonrise and moonset

The 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.

Moon phase and lunation details

Moon in ♎ Libra

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

4 days after Full Moon

Previous main lunar phase is the Full Moon before 4 days on 14 February 2052 at 18:21.

Snow Moon before 4 days

Next Full Moon is the Worm Moon of March 2052 after 24 days on 15 March 2052 at 09:54.

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 ∠1774"

Lunar disc appears visually 9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1774" and ∠1941".

Lunation 644 / 1597

The Moon is 19 days old and navigating from the middle to the last part of the current synodic month. This is lunation 644 of Meeus index or 1597 from Brown series.

Synodic month length 29.55 days

The length of this lunation is 29 days, 13 hours and 6 minutes and it is 2 hours and 15 minutes longer than the upcoming lunation's length. 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 22 minutes longer than the mean synodic month length. It is 6 hours and 41 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠285.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠285.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠314.8°.

Moon before apogee

12 days since point of perigee on 6 February 2052 at 18:01 in ♈ Aries the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next day until the Moon reaches the point of next apogee on 21 February 2052 at 10:01 in ♏ Scorpio.

Distance to Moon 404 028 km

The Moon is 404 028 km (251 051 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 404 402 km (251 284 mi).

Moon after ascending node

1 day after ascending node on 18 February 2052 at 16:11 in ♎ Libra the Moon is positioned north of the ecliptic over the following 13 days until the lunar crosses the ecliptic again from North to South in descending node on 3 March 2052 at 14:47 in ♈ Aries.

Moon before southern standstill

9 days since the last northern standstill on 10 February 2052 at 09:08 in ♊ Gemini when the Moon has reached North declination of ∠18.554° the lunar orbit is extending southward over the next 5 days to face maximum declination of ∠-18.455° at the point of next southern standstill on 24 February 2052 at 14:50 in ♐ Sagittarius.

Draconic month

1 day since the beginning of this draconic month in ♎ Libra the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 10 days

In 10 days on 1 March 2052 at 07:36 in ♓ Pisces 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.
