Waning Gibbous in Virgo

Waning Gibbous on . Illuminated surface of the Moon is 62% and getting smaller. Lunar cycle is 21 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 ♍ Virgo

Moon is passing about ∠16° of ♍ Virgo tropical zodiac sector.

6 days after Full Moon

Previous main lunar phase is the Full Moon before 6 days on 15 December 2005 at 16:16.

Cold Moon before 6 days

Next Full Moon is the Wolf Moon of January 2006 after 22 days on 14 January 2006 at 09:48.

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 ∠1774"

Lunar disc appears visually 9.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1774" and ∠1951".

Lunation 73 / 1026

The Moon is 21 days old and navigating from the middle to the last part of the current synodic month. This is lunation 73 of Meeus index or 1026 from Brown series.

Synodic month length 29.51 days

The length of this lunation is 29 days, 12 hours and 11 minutes and it is 1 hour and 8 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 33 minutes shorter than the mean synodic month length. It is 5 hours and 36 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠306.3°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠306.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠329.9°.

Moon after apogee

1 day since point of apogee on 21 December 2005 at 02:49 in ♍ Virgo 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 1 January 2006 at 22:50 in ♑ Capricorn.

Distance to Moon 404 142 km

The Moon is 404 142 km (251 122 mi) away from Earth and getting closer over the next 10 days until the point perigee when Earth-Moon distance is going to be 361 750 km (224 781 mi).

Moon before descending node

12 days after ascending node on 10 December 2005 at 04:50 in ♈ Aries the Moon is positioned north of the ecliptic over the following day until the lunar crosses the ecliptic again from North to South in descending node on 24 December 2005 at 10:43 in ♎ Libra.

Moon after northern standstill

6 days since the last northern standstill on 16 December 2005 at 07:14 in ♋ Cancer when the Moon has reached North declination of ∠28.378° the lunar orbit is extending southward over the next 8 days to face maximum declination of ∠-28.387° at the point of next southern standstill on 30 December 2005 at 13:57 in ♐ Sagittarius.

Draconic month

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

Syzygy in 8 days

In 8 days on 31 December 2005 at 03:12 in ♑ Capricorn 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.
