Last Quarter in Aries

Last Quarter on . The illuminated surface of the moon is 58% and getting smaller. The lunar cycle is 21 days old.

* The exact date and time of this Last Quarter phase is on 19 July 2033 at 04:07 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 ∠17° of ♈ Aries tropical zodiac sector.

Sturgeon Moon after 23 days

Next Full Moon is the Sturgeon Moon of August 2033 after 23 days on 10 August 2033 at 18:08.

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 4.3% wider than solar disc. Moon and Sun apparent angular diameters are ∠1972" and ∠1888".

Lunation 414 / 1367

The Moon is 21 days old and navigating through the last part of the current synodic month. This is lunation 414 of Meeus index or 1367 from Brown series.

Synodic month length 29.46 days

The length of this lunation is 29 days, 11 hours and 6 minutes and it is 2 hours and 21 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 1 hour and 39 minutes shorter than the mean synodic month length. It is 4 hours and 31 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠74.1°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠74.1° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠108.5°.

Moon after perigee

2 days since point of perigee on 16 July 2033 at 09:27 in ♓ Pisces the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 13 days until the Moon reaches the point of next apogee on 31 July 2033 at 23:13 in ♎ Libra.

Distance to Moon 363 523 km

The Moon is 363 523 km (225 883 mi) away from Earth and getting further over the next 13 days until the point apogee when Earth-Moon distance is going to be 404 734 km (251 490 mi).

Moon in descending node

Moon is in descending node in ♈ Aries at 09:20 crossing the ecliptic from North to South. Lunar position remains south of if for the upcoming 13 days until Moon's next ascending node later on 1 August 2033 at 03:38 in ♎ Libra.

Moon before northern standstill

7 days since the last southern standstill on 10 July 2033 at 14:02 in ♐ Sagittarius when the Moon has reached South declination of ∠-18.676° the lunar orbit is extending northward over the next 4 days to face maximum declination of ∠18.624° at the point of next northern standstill on 23 July 2033 at 11:24 in ♊ Gemini.

Draconic month

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

Syzygy in 7 days

In 7 days on 26 July 2033 at 08:12 in ♌ Leo 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.
