Waning Gibbous in Libra

Waning Gibbous on . The illuminated surface of the moon is 82% and getting smaller. The lunar cycle is 19 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 ∠12° of ♎ Libra tropical zodiac sector.

4 days after Full Moon

Previous main lunar phase is the Full Moon before 4 days on 6 February 2004 at 08:47.

Snow Moon before 4 days

Next Full Moon is the Worm Moon of March 2004 after 25 days on 6 March 2004 at 23:14.

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 ∠1922"

Lunar disc appears visually 1.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1922" and ∠1944".

Lunation 50 / 1003

The Moon is 19 days old and navigating from the middle to the last part of the current synodic month. This is lunation 50 of Meeus index or 1003 from Brown series.

Synodic month length 29.51 days

The length of this lunation is 29 days, 12 hours and 13 minutes and it is 1 hour and 11 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 shorter than mean

The length of the current synodic month is 31 minutes shorter than the mean synodic month length. It is 5 hours and 38 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠33.9°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠33.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠59.1°.

Moon before perigee

9 days since point of apogee on 31 January 2004 at 14:00 in ♊ Gemini the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 5 days until the Moon reaches the point of next perigee on 16 February 2004 at 07:34 in ♑ Capricorn.

Distance to Moon 372 883 km

The Moon is 372 883 km (231 699 mi) away from Earth and getting closer over the next 5 days until the point perigee when Earth-Moon distance is going to be 368 320 km (228 863 mi).

Moon before descending node

11 days after ascending node on 29 January 2004 at 22:07 in ♉ Taurus the Moon is positioned north of the ecliptic over the following 2 days until the lunar crosses the ecliptic again from North to South in descending node on 12 February 2004 at 21:44 in ♏ Scorpio.

Moon before southern standstill

7 days since the last northern standstill on 3 February 2004 at 04:10 in ♋ Cancer when the Moon has reached North declination of ∠27.131° the lunar orbit is extending southward over the next 6 days to face maximum declination of ∠-27.229° at the point of next southern standstill on 16 February 2004 at 13:51 in ♐ Sagittarius.

Draconic month

11 days since the beginning of this draconic month in ♉ Taurus the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 9 days

In 9 days on 20 February 2004 at 09:18 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.
