Waning Gibbous in Libra

Waning Gibbous on . Illuminated surface of the Moon is 97% and getting smaller. Lunar cycle is 16 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 leaving the last ∠4° of ♎ Libra tropical zodiac sector and will enter ♏ Scorpio later.

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 25 March 2005 at 20:58.

Worm Moon before 1 day

Next Full Moon is the Pink Moon of April 2005 after 27 days on 24 April 2005 at 10:06.

Moderate tide

There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.

Apparent angular diameter ∠1869"

Lunar disc appears visually 2.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1869" and ∠1922".

Lunation 64 / 1017

The Moon is 16 days old and navigating from the middle to the last part of the current synodic month. This is lunation 64 of Meeus index or 1017 from Brown series.

Synodic month length 29.47 days

The length of this lunation is 29 days, 11 hours and 22 minutes and it is 51 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 1 hour and 22 minutes shorter than the mean synodic month length. It is 4 hours and 47 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠36.2°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠36.2° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠62.3°.

Moon after apogee

7 days since point of apogee on 19 March 2005 at 22:54 in ♋ Cancer the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 7 days until the Moon reaches the point of next perigee on 4 April 2005 at 11:10 in ♒ Aquarius.

Distance to Moon 383 488 km

The Moon is 383 488 km (238 288 mi) away from Earth and getting closer over the next 7 days until the point perigee when Earth-Moon distance is going to be 368 492 km (228 970 mi).

Moon in descending node

Moon is in descending node in ♎ Libra at 05:15 crossing the ecliptic from North to South. Lunar position remains south of if for the upcoming 12 days until Moon's next ascending node later on 9 April 2005 at 02:59 in ♈ Aries.

Moon before southern standstill

9 days since the last northern standstill on 18 March 2005 at 08:25 in ♋ Cancer when the Moon has reached North declination of ∠28.325° the lunar orbit is extending southward over the next 4 days to face maximum declination of ∠-28.372° at the point of next southern standstill on 1 April 2005 at 10:19 in ♑ Capricorn.

Draconic month

14 days since the beginning of this draconic month in ♈ Aries the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 12 days

In 12 days on 8 April 2005 at 20:32 in ♈ Aries 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.
