Waning Gibbous in Libra

Waning Gibbous on . The illuminated surface of the moon is 68% and getting smaller. The lunar cycle is 20 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 leaving the last ∠2° of ♎ Libra tropical zodiac sector and will enter ♏ Scorpio later.

6 days after Full Moon

Previous main lunar phase is the Full Moon before 6 days on 2 February 2007 at 05:45.

Snow Moon before 6 days

Next Full Moon is the Worm Moon of March 2007 after 23 days on 3 March 2007 at 23:17.

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 ∠1771"

Lunar disc appears visually 9.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1771" and ∠1945".

Lunation 87 / 1040

The Moon is 20 days old and navigating from the middle to the last part of the current synodic month. This is lunation 87 of Meeus index or 1040 from Brown series.

Synodic month length 29.51 days

The length of this lunation is 29 days, 12 hours and 14 minutes and it is 1 hour and 46 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 30 minutes shorter than the mean synodic month length. It is 5 hours and 39 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠308.6°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠308.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠331.4°.

Moon after apogee

1 day since point of apogee on 7 February 2007 at 12:39 in ♎ Libra the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 10 days until the Moon reaches the point of next perigee on 19 February 2007 at 09:34 in ♓ Pisces.

Distance to Moon 404 663 km

The Moon is 404 663 km (251 446 mi) away from Earth and getting closer over the next 10 days until the point perigee when Earth-Moon distance is going to be 361 440 km (224 588 mi).

Moon after descending node

3 days after descending node on 4 February 2007 at 22:44 in ♍ Virgo the Moon is positioned south of the ecliptic over the following 10 days until the lunar crosses the ecliptic again from South to North in ascending node on 18 February 2007 at 20:43 in ♓ Pisces.

Moon before southern standstill

9 days since the last northern standstill on 29 January 2007 at 18:19 in ♊ Gemini when the Moon has reached North declination of ∠28.501° the lunar orbit is extending southward over the next 4 days to face maximum declination of ∠-28.568° at the point of next southern standstill on 13 February 2007 at 07:33 in ♐ Sagittarius.

Draconic month

16 days since the beginning of this draconic month in ♓ Pisces the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 9 days

In 9 days on 17 February 2007 at 16:14 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.
