Last Quarter in Virgo

Last Quarter on . Illuminated surface of the Moon is 56% and getting smaller. Lunar cycle is 21 days old.

* The exact date and time of this Last Quarter phase is on 21 December 2016 at 01:56 UTC.

Moonrise and moonset

Moon rises at midnight and sets at noon. It is visible to the south in the morning.

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon in ♍ Virgo

Moon is passing about ∠22° of ♍ Virgo tropical zodiac sector.

Wolf Moon after 22 days

Next Full Moon is the Wolf Moon of January 2017 after 22 days on 12 January 2017 at 11:34.

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 ∠1821"

Lunar disc appears visually 6.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1821" and ∠1950".

Lunation 209 / 1162

The Moon is 21 days old and navigating through the last part of the current synodic month. This is lunation 209 of Meeus index or 1162 from Brown series.

Synodic month length 29.77 days

The length of this lunation is 29 days, 18 hours and 35 minutes and it is 1 hour and 21 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 longer than mean

The length of the current synodic month is 5 hours and 51 minutes longer than the mean synodic month length. It is 1 hour and 12 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠194.9°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠194.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠223.4°.

Moon before apogee

7 days since point of perigee on 12 December 2016 at 23:27 in ♉ Taurus the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 4 days until the Moon reaches the point of next apogee on 25 December 2016 at 05:55 in ♏ Scorpio.

Distance to Moon 393 569 km

The Moon is 393 569 km (244 552 mi) away from Earth and getting further over the next 4 days until the point apogee when Earth-Moon distance is going to be 405 870 km (252 196 mi).

Moon after ascending node

1 day after ascending node on 19 December 2016 at 04:46 in ♍ Virgo the Moon is positioned north of the ecliptic over the following 13 days until the lunar crosses the ecliptic again from North to South in descending node on 2 January 2017 at 18:14 in ♒ Aquarius.

Moon after northern standstill

5 days since the last northern standstill on 14 December 2016 at 21:43 in ♊ Gemini when the Moon has reached North declination of ∠18.937° the lunar orbit is extending southward over the next 8 days to face maximum declination of ∠-18.958° at the point of next southern standstill on 29 December 2016 at 03:30 in ♑ Capricorn.

Draconic month

1 day since the beginning of this draconic month in ♍ Virgo the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 8 days

In 8 days on 29 December 2016 at 06:53 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.
