Waning Gibbous in Libra

Waning Gibbous on . The illuminated surface of the moon is 95% and getting smaller. The lunar cycle is 17 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 ∠13° of ♎ Libra tropical zodiac sector.

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 5 March 2091 at 15:59.

Worm Moon before 1 day

Next Full Moon is the Pink Moon of April 2091 after 27 days on 4 April 2091 at 01:31.

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 ∠1973"

Lunar disc appears visually 2% wider than solar disc. Moon and Sun apparent angular diameters are ∠1973" and ∠1933".

Lunation 1127 / 2080

The Moon is 17 days old and navigating from the middle to the last part of the current synodic month. This is lunation 1127 of Meeus index or 2080 from Brown series.

Synodic month length 29.75 days

The length of this lunation is 29 days, 18 hours and 7 minutes and it is 33 minutes longer than the upcoming lunation's length. This is the year's longest synodic month of 2091. 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 23 minutes longer than the mean synodic month length. It is 1 hour and 40 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠137.9°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠137.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠165.8°.

Moon after perigee

1 day since point of perigee on 6 March 2091 at 16:02 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 14 days until the Moon reaches the point of next apogee on 21 March 2091 at 17:48 in ♈ Aries.

Distance to Moon 363 302 km

The Moon is 363 302 km (225 745 mi) away from Earth and getting further over the next 14 days until the point apogee when Earth-Moon distance is going to be 406 436 km (252 548 mi).

Moon after ascending node

2 days after ascending node on 5 March 2091 at 10:19 in ♍ Virgo the Moon is positioned north of the ecliptic over the following 11 days until the lunar crosses the ecliptic again from North to South in descending node on 18 March 2091 at 15:30 in ♓ Pisces.

Moon before southern standstill

6 days since the last northern standstill on 28 February 2091 at 16:49 in ♊ Gemini when the Moon has reached North declination of ∠18.473° the lunar orbit is extending southward over the next 5 days to face maximum declination of ∠-18.480° at the point of next southern standstill on 13 March 2091 at 06:18 in ♑ Capricorn.

Draconic month

2 days since the beginning of this draconic month in ♍ Virgo the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 12 days

In 12 days on 20 March 2091 at 03:45 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.
