Waning Gibbous in Virgo

Waning Gibbous on . Illuminated surface of the Moon is 84% and getting smaller. Lunar cycle is 18 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 ∠17° of ♍ Virgo tropical zodiac sector.

4 days after Full Moon

Previous main lunar phase is the Full Moon before 4 days on 16 January 2014 at 04:52.

Wolf Moon before 4 days

Next Full Moon is the Snow Moon of February 2014 after 25 days on 14 February 2014 at 23:53.

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 ∠1806"

Lunar disc appears visually 7.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1806" and ∠1950".

Lunation 173 / 1126

The Moon is 18 days old and navigating from the middle to the last part of the current synodic month. This is lunation 173 of Meeus index or 1126 from Brown series.

Synodic month length 29.43 days

The length of this lunation is 29 days, 10 hours and 24 minutes and it is 3 minutes longer 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 2 hours and 20 minutes shorter than the mean synodic month length. It is 3 hours and 49 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠353°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠353° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠8.3°.

Moon after apogee

4 days since point of apogee on 16 January 2014 at 01:53 in ♋ Cancer 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 30 January 2014 at 09:58 in ♒ Aquarius.

Distance to Moon 396 888 km

The Moon is 396 888 km (246 615 mi) away from Earth and getting closer over the next 9 days until the point perigee when Earth-Moon distance is going to be 357 080 km (221 879 mi).

Moon before ascending node

11 days after descending node on 9 January 2014 at 11:26 in ♉ Taurus the Moon is positioned south of the ecliptic over the following 3 days until the lunar crosses the ecliptic again from South to North in ascending node on 24 January 2014 at 02:55 in ♏ Scorpio.

Moon after northern standstill

7 days since the last northern standstill on 13 January 2014 at 08:14 in ♊ Gemini when the Moon has reached North declination of ∠19.501° the lunar orbit is extending southward over the next 7 days to face maximum declination of ∠-19.396° at the point of next southern standstill on 27 January 2014 at 16:31 in ♐ Sagittarius.

Draconic month

23 days since the beginning of this draconic month in ♏ Scorpio the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 10 days

In 10 days on 30 January 2014 at 21:39 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.
