Last Quarter in Aries

Last Quarter on . The illuminated surface of the moon is 56% and getting smaller. The lunar cycle is 21 days old.

* The exact date and time of this Last Quarter phase is on 27 July 2073 at 04:29 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 leaving the last ∠3° of ♈ Aries tropical zodiac sector and will enter ♉ Taurus later.

Sturgeon Moon after 22 days

Next Full Moon is the Sturgeon Moon of August 2073 after 22 days on 17 August 2073 at 17:45.

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 ∠1769"

Lunar disc appears visually 6.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1769" and ∠1889".

Lunation 909 / 1862

The Moon is 21 days old and navigating through the last part of the current synodic month. This is lunation 909 of Meeus index or 1862 from Brown series.

Synodic month length 29.41 days

The length of this lunation is 29 days, 9 hours and 48 minutes and it is 59 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 shorter than mean

The length of the current synodic month is 2 hours and 56 minutes shorter than the mean synodic month length. It is 3 hours and 13 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠284.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠284.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠313.1°.

Moon after apogee

1 day since point of apogee on 25 July 2073 at 19:45 in ♈ Aries the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 11 days until the Moon reaches the point of next perigee on 6 August 2073 at 17:22 in ♍ Virgo.

Distance to Moon 405 160 km

The Moon is 405 160 km (251 755 mi) away from Earth and getting closer over the next 11 days until the point perigee when Earth-Moon distance is going to be 365 543 km (227 138 mi).

Moon after descending node

5 days after descending node on 21 July 2073 at 02:27 in ♒ Aquarius the Moon is positioned south of the ecliptic over the following 8 days until the lunar crosses the ecliptic again from South to North in ascending node on 4 August 2073 at 08:57 in ♌ Leo.

Moon before northern standstill

8 days since the last southern standstill on 17 July 2073 at 20:15 in ♑ Capricorn when the Moon has reached South declination of ∠-19.591° the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠19.570° at the point of next northern standstill on 1 August 2073 at 07:46 in ♋ Cancer.

Draconic month

18 days since the beginning of this draconic month in ♌ Leo the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 8 days

In 8 days on 3 August 2073 at 17:04 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.
