Last Quarter in Aries

Last Quarter on . The illuminated surface of the moon is 55% and getting smaller. The lunar cycle is 21 days old.

* The exact date and time of this Last Quarter phase is on 22 July 2087 at 22:43 UTC.

Moonrise and moonset

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

Moon phase and lunation details

Moon in ♈ Aries

Moon is passing about ∠24° of ♈ Aries tropical zodiac sector.

Sturgeon Moon after 22 days

Next Full Moon is the Sturgeon Moon of August 2087 after 22 days on 14 August 2087 at 06:54.

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 ∠1966"

Lunar disc appears visually 4% wider than solar disc. Moon and Sun apparent angular diameters are ∠1966" and ∠1889".

Lunation 1082 / 2035

The Moon is 21 days old and navigating through the last part of the current synodic month. This is lunation 1082 of Meeus index or 2035 from Brown series.

Synodic month length 29.37 days

The length of this lunation is 29 days, 8 hours and 49 minutes and it is 1 hour and 59 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 3 hours and 55 minutes shorter than the mean synodic month length. It is 2 hours and 14 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠37.8°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠37.8° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠62.7°.

Moon before perigee

12 days since point of apogee on 9 July 2087 at 22:18 in ♏ Scorpio the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 2 days until the Moon reaches the point of next perigee on 25 July 2087 at 08:02 in ♊ Gemini.

Distance to Moon 364 664 km

The Moon is 364 664 km (226 592 mi) away from Earth and getting closer over the next 2 days until the point perigee when Earth-Moon distance is going to be 368 392 km (228 908 mi).

Moon before descending node

11 days after ascending node on 10 July 2087 at 23:01 in ♏ Scorpio the Moon is positioned north of the ecliptic over the following 2 days until the lunar crosses the ecliptic again from North to South in descending node on 24 July 2087 at 12:18 in ♉ Taurus.

Moon before northern standstill

9 days since the last southern standstill on 13 July 2087 at 01:52 in ♐ Sagittarius when the Moon has reached South declination of ∠-20.759° the lunar orbit is extending northward over the next 3 days to face maximum declination of ∠20.684° at the point of next northern standstill on 26 July 2087 at 09:39 in ♊ Gemini.

Draconic month

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

Syzygy in 7 days

In 7 days on 29 July 2087 at 18:20 in ♋ Cancer 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.
