Last Quarter in Aries

Last Quarter on . The illuminated surface of the moon is 48% and getting smaller. The lunar cycle is 22 days old.

* The exact date and time of this Last Quarter phase is on 1 July 2051 at 07:15 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 ∠12° of ♈ Aries tropical zodiac sector.

Buck Moon after 22 days

Next Full Moon is the Buck Moon of July 2051 after 22 days on 23 July 2051 at 16:36.

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 ∠1972"

Lunar disc appears visually 4.4% wider than solar disc. Moon and Sun apparent angular diameters are ∠1972" and ∠1887".

Lunation 636 / 1589

The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 636 of Meeus index or 1589 from Brown series.

Synodic month length 29.38 days

The length of this lunation is 29 days, 9 hours and 13 minutes and it is 1 hour and 43 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 31 minutes shorter than the mean synodic month length. It is 2 hours and 38 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠43.2°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠43.2° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠70.2°.

Moon before perigee

13 days since point of apogee on 17 June 2051 at 22:14 in ♎ Libra the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next day until the Moon reaches the point of next perigee on 2 July 2051 at 20:59 in ♈ Aries.

Distance to Moon 363 421 km

The Moon is 363 421 km (225 819 mi) away from Earth and getting closer over the next day until the point perigee when Earth-Moon distance is going to be 369 221 km (229 423 mi).

Moon before descending node

12 days after ascending node on 19 June 2051 at 06:50 in ♏ Scorpio 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 2 July 2051 at 17:54 in ♈ Aries.

Moon before northern standstill

8 days since the last southern standstill on 23 June 2051 at 11:15 in ♐ Sagittarius when the Moon has reached South declination of ∠-19.227° the lunar orbit is extending northward over the next 4 days to face maximum declination of ∠19.198° at the point of next northern standstill on 6 July 2051 at 11:58 in ♊ Gemini.

Draconic month

12 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 6 days

In 6 days on 8 July 2051 at 04:09 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.
