Waning Gibbous in Libra

Waning Gibbous on . Illuminated surface of the Moon is 85% and getting smaller. Lunar cycle is 18 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 is entering ♎ Libra

Moon is passing first ∠4° of ♎ Libra tropical zodiac sector.

3 days after Full Moon

Previous main lunar phase is the Full Moon before 3 days on 4 February 2091 at 04:46.

Snow Moon before 3 days

Next Full Moon is the Worm Moon of March 2091 after 26 days on 5 March 2091 at 15:59.

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 ∠1972"

Lunar disc appears visually 1.4% wider than solar disc. Moon and Sun apparent angular diameters are ∠1972" and ∠1945".

Lunation 1126 / 2079

The Moon is 18 days old and navigating from the middle to the last part of the current synodic month. This is lunation 1126 of Meeus index or 2079 from Brown series.

Synodic month length 29.71 days

The length of this lunation is 29 days, 17 hours and 7 minutes and it is 1 hour 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 4 hours and 23 minutes longer than the mean synodic month length. It is 2 hours and 40 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠102°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠102° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠137.9°.

Moon after perigee

1 day since point of perigee on 6 February 2091 at 09:12 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 22 February 2091 at 08:37 in ♈ Aries.

Distance to Moon 363 446 km

The Moon is 363 446 km (225 835 mi) away from Earth and getting further over the next 14 days until the point apogee when Earth-Moon distance is going to be 405 740 km (252 115 mi).

Moon after ascending node

1 day after ascending node on 5 February 2091 at 23:52 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 19 February 2091 at 08:56 in ♓ Pisces.

Moon after northern standstill

6 days since the last northern standstill on 1 February 2091 at 06:49 in ♋ Cancer when the Moon has reached North declination of ∠18.537° the lunar orbit is extending southward over the next 6 days to face maximum declination of ∠-18.496° at the point of next southern standstill on 14 February 2091 at 00:36 in ♑ Capricorn.

Draconic month

1 day 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 10 days

In 10 days on 18 February 2091 at 09:38 in ♒ Aquarius 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.
