Waning Gibbous in Libra

Waning Gibbous on . Illuminated surface of the Moon is 75% 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 ∠20° of ♎ Libra tropical zodiac sector.

5 days after Full Moon

Previous main lunar phase is the Full Moon before 5 days on 3 February 2015 at 23:09.

Snow Moon before 5 days

Next Full Moon is the Worm Moon of March 2015 after 24 days on 5 March 2015 at 18:06.

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 ∠1793"

Lunar disc appears visually 8.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1793" and ∠1945".

Lunation 186 / 1139

The Moon is 19 days old and navigating from the middle to the last part of the current synodic month. This is lunation 186 of Meeus index or 1139 from Brown series.

Synodic month length 29.44 days

The length of this lunation is 29 days, 10 hours and 34 minutes and it is 45 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 shorter than mean

The length of the current synodic month is 2 hours and 10 minutes shorter than the mean synodic month length. It is 3 hours and 59 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠338.3°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠338.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠354.5°.

Moon after apogee

3 days since point of apogee on 6 February 2015 at 06:25 in ♍ Virgo the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 9 days until the Moon reaches the point of next perigee on 19 February 2015 at 07:29 in ♓ Pisces.

Distance to Moon 399 684 km

The Moon is 399 684 km (248 352 mi) away from Earth and getting closer over the next 9 days until the point perigee when Earth-Moon distance is going to be 356 992 km (221 825 mi).

Moon after ascending node

1 day after ascending node on 8 February 2015 at 17:10 in ♎ Libra the Moon is positioned north of the ecliptic over the following 12 days until the lunar crosses the ecliptic again from North to South in descending node on 21 February 2015 at 16:05 in ♈ Aries.

Moon before southern standstill

9 days since the last northern standstill on 31 January 2015 at 00:59 in ♋ Cancer when the Moon has reached North declination of ∠18.513° the lunar orbit is extending southward over the next 5 days to face maximum declination of ∠-18.402° at the point of next southern standstill on 14 February 2015 at 17:17 in ♐ Sagittarius.

Draconic month

1 day since the beginning of this draconic month in ♎ Libra the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 9 days

In 9 days on 18 February 2015 at 23:47 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.
