Waning Gibbous in Libra

Waning Gibbous on . Illuminated surface of the Moon is 81% and getting smaller. Lunar cycle is 19 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 ∠22° of ♎ Libra tropical zodiac sector.

4 days after Full Moon

Previous main lunar phase is the Full Moon before 4 days on 14 February 2014 at 23:53.

Snow Moon before 4 days

Next Full Moon is the Worm Moon of March 2014 after 25 days on 16 March 2014 at 17:09.

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 ∠1857"

Lunar disc appears visually 4.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1857" and ∠1941".

Lunation 174 / 1127

The Moon is 19 days old and navigating from the middle to the last part of the current synodic month. This is lunation 174 of Meeus index or 1127 from Brown series.

Synodic month length 29.43 days

The length of this lunation is 29 days, 10 hours and 21 minutes and it is 24 minutes shorter than the upcoming lunation's length. This is the year's shortest synodic month of 2014. 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 shorter than mean

The length of the current synodic month is 2 hours and 23 minutes shorter than the mean synodic month length. It is 3 hours and 46 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠8.3°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠8.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠25.1°.

Moon after apogee

7 days since point of apogee on 12 February 2014 at 05:09 in ♋ Cancer the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 8 days until the Moon reaches the point of next perigee on 27 February 2014 at 19:52 in ♒ Aquarius.

Distance to Moon 386 088 km

The Moon is 386 088 km (239 904 mi) away from Earth and getting closer over the next 8 days until the point perigee when Earth-Moon distance is going to be 360 439 km (223 966 mi).

Moon before ascending node

13 days after descending node on 5 February 2014 at 12:41 in ♉ Taurus the Moon is positioned south of the ecliptic over the following day until the lunar crosses the ecliptic again from South to North in ascending node on 20 February 2014 at 03:28 in ♎ Libra.

Moon before southern standstill

9 days since the last northern standstill on 9 February 2014 at 15:21 in ♊ Gemini when the Moon has reached North declination of ∠19.306° the lunar orbit is extending southward over the next 4 days to face maximum declination of ∠-19.175° at the point of next southern standstill on 24 February 2014 at 01:24 in ♐ Sagittarius.

Draconic month

26 days since the beginning of this draconic month in ♏ Scorpio the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 9 days

In 9 days on 1 March 2014 at 08:00 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.
