Waning Gibbous in Libra

Waning Gibbous on . Illuminated surface of the Moon is 97% and getting smaller. Lunar cycle is 16 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 leaving the last ∠3° of ♎ Libra tropical zodiac sector and will enter ♏ Scorpio later.

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 25 March 2081 at 00:29.

Worm Moon before 1 day

Next Full Moon is the Pink Moon of April 2081 after 27 days on 23 April 2081 at 10:20.

Moderate tide

There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.

Apparent angular diameter ∠1926"

Lunar disc appears visually 0.2% wider than solar disc. Moon and Sun apparent angular diameters are ∠1926" and ∠1923".

Lunation 1004 / 1957

The Moon is 16 days old and navigating from the middle to the last part of the current synodic month. This is lunation 1004 of Meeus index or 1957 from Brown series.

Synodic month length 29.71 days

The length of this lunation is 29 days, 16 hours and 58 minutes and it is 3 hours and 4 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 4 hours and 14 minutes longer than the mean synodic month length. It is 2 hours and 49 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠202.2°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠202.2° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠231.2°.

Moon after perigee

2 days since point of perigee on 23 March 2081 at 16:38 in ♍ Virgo the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 9 days until the Moon reaches the point of next apogee on 4 April 2081 at 19:49 in ♒ Aquarius.

Distance to Moon 372 182 km

The Moon is 372 182 km (231 263 mi) away from Earth and getting further over the next 9 days until the point apogee when Earth-Moon distance is going to be 405 494 km (251 962 mi).

Moon after descending node

2 days after descending node on 24 March 2081 at 07:17 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 7 April 2081 at 05:10 in ♓ Pisces.

Moon before southern standstill

8 days since the last northern standstill on 18 March 2081 at 10:34 in ♊ Gemini when the Moon has reached North declination of ∠28.673° the lunar orbit is extending southward over the next 4 days to face maximum declination of ∠-28.653° at the point of next southern standstill on 31 March 2081 at 02:35 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 13 days

In 13 days on 9 April 2081 at 08:15 in ♈ Aries 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.
