Waning Gibbous in Libra

Waning Gibbous on . Illuminated surface of the Moon is 62% and getting smaller. Lunar cycle is 21 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 ∠12° of ♎ Libra tropical zodiac sector.

5 days after Full Moon

Previous main lunar phase is the Full Moon before 5 days on 10 January 2020 at 19:21.

Wolf Moon before 5 days

Next Full Moon is the Snow Moon of February 2020 after 23 days on 9 February 2020 at 07:33.

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 ∠1971"

Lunar disc appears visually 1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1971" and ∠1951".

Lunation 247 / 1200

The Moon is 21 days old and navigating from the middle to the last part of the current synodic month. This is lunation 247 of Meeus index or 1200 from Brown series.

Synodic month length 29.69 days

The length of this lunation is 29 days, 16 hours and 29 minutes and it is 1 hour and 21 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 3 hours and 45 minutes longer than the mean synodic month length. It is 3 hours and 18 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠82.6°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠82.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠120.5°.

Moon after perigee

2 days since point of perigee on 13 January 2020 at 20:20 in ♌ Leo the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 13 days until the Moon reaches the point of next apogee on 29 January 2020 at 21:28 in ♓ Pisces.

Distance to Moon 363 761 km

The Moon is 363 761 km (226 031 mi) away from Earth and getting further over the next 13 days until the point apogee when Earth-Moon distance is going to be 405 390 km (251 898 mi).

Moon before descending node

6 days after ascending node on 9 January 2020 at 23:29 in ♋ Cancer the Moon is positioned north of the ecliptic over the following 6 days until the lunar crosses the ecliptic again from North to South in descending node on 22 January 2020 at 20:31 in ♑ Capricorn.

Moon after northern standstill

6 days since the last northern standstill on 10 January 2020 at 06:03 in ♋ Cancer when the Moon has reached North declination of ∠23.223° the lunar orbit is extending southward over the next 6 days to face maximum declination of ∠-23.225° at the point of next southern standstill on 23 January 2020 at 03:37 in ♑ Capricorn.

Draconic month

6 days since the beginning of this draconic month in ♋ Cancer the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 8 days

In 8 days on 24 January 2020 at 21:42 in ♑ Capricorn 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.
