Last Quarter in Sagittarius

Last Quarter on . Illuminated surface of the Moon is 52% and getting smaller. Lunar cycle is 22 days old.

* The exact date and time of this Last Quarter phase is on 13 March 2015 at 17:48 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 ♐ Sagittarius

Moon is passing about ∠20° of ♐ Sagittarius tropical zodiac sector.

Pink Moon after 22 days

Next Full Moon is the Pink Moon of April 2015 after 22 days on 4 April 2015 at 12:06.

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 ∠1884"

Lunar disc appears visually 2.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1884" and ∠1930".

Lunation 187 / 1140

The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 187 of Meeus index or 1140 from Brown series.

Synodic month length 29.41 days

The length of this lunation is 29 days, 9 hours and 49 minutes and it is 28 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 55 minutes shorter than the mean synodic month length. It is 3 hours and 14 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠354.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠354.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠9.9°.

Moon before perigee

8 days since point of apogee on 5 March 2015 at 07:35 in ♍ Virgo the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 6 days until the Moon reaches the point of next perigee on 19 March 2015 at 19:38 in ♓ Pisces.

Distance to Moon 380 415 km

The Moon is 380 415 km (236 379 mi) away from Earth and getting closer over the next 6 days until the point perigee when Earth-Moon distance is going to be 357 584 km (222 192 mi).

Moon after ascending node

5 days after ascending node on 7 March 2015 at 21:04 in ♎ Libra the Moon is positioned north of the ecliptic over the following 7 days until the lunar crosses the ecliptic again from North to South in descending node on 21 March 2015 at 02:19 in ♈ Aries.

Moon before southern standstill

14 days since the last northern standstill on 27 February 2015 at 07:19 in ♊ Gemini when the Moon has reached North declination of ∠18.335° the lunar orbit is extending southward over the next day to face maximum declination of ∠-18.262° at the point of next southern standstill on 14 March 2015 at 01:39 in ♐ Sagittarius.

Draconic month

5 days since the beginning of this draconic month in ♎ Libra the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 6 days

In 6 days on 20 March 2015 at 09:36 in ♓ Pisces 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.
