Waning Gibbous in Libra

Waning Gibbous on . Illuminated surface of the Moon is 94% and getting smaller. Lunar cycle is 17 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 ♎ Libra

Moon is passing about ∠10° of ♎ Libra tropical zodiac sector.

2 days after Full Moon

Previous main lunar phase is the Full Moon before 2 days on 27 February 2021 at 08:17.

Snow Moon before 2 days

Next Full Moon is the Worm Moon of March 2021 after 27 days on 28 March 2021 at 18:48.

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 ∠1954"

Lunar disc appears visually 0.9% wider than solar disc. Moon and Sun apparent angular diameters are ∠1954" and ∠1936".

Lunation 261 / 1214

The Moon is 17 days old and navigating from the middle to the last part of the current synodic month. This is lunation 261 of Meeus index or 1214 from Brown series.

Synodic month length 29.64 days

The length of this lunation is 29 days, 15 hours and 15 minutes and it is 55 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 2 hours and 31 minutes longer than the mean synodic month length. It is 4 hours and 32 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠87°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠87° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠124.3°.

Moon before perigee

11 days since point of apogee on 18 February 2021 at 10:22 in ♉ Taurus 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 2 March 2021 at 05:19 in ♎ Libra.

Distance to Moon 366 780 km

The Moon is 366 780 km (227 907 mi) away from Earth and getting closer over the next day until the point perigee when Earth-Moon distance is going to be 365 422 km (227 063 mi).

Moon before descending node

8 days after ascending node on 21 February 2021 at 01:44 in ♊ Gemini the Moon is positioned north of the ecliptic over the following 4 days until the lunar crosses the ecliptic again from North to South in descending node on 6 March 2021 at 00:56 in ♐ Sagittarius.

Moon before southern standstill

6 days since the last northern standstill on 23 February 2021 at 00:12 in ♋ Cancer when the Moon has reached North declination of ∠25.056° the lunar orbit is extending southward over the next 6 days to face maximum declination of ∠-25.161° at the point of next southern standstill on 7 March 2021 at 20:45 in ♑ Capricorn.

Draconic month

8 days since the beginning of this draconic month in ♊ Gemini the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 11 days

In 11 days on 13 March 2021 at 10:21 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.
