Last Quarter in Aries

Last Quarter on . The illuminated surface of the moon is 45% and getting smaller. The lunar cycle is 22 days old.

* The exact date and time of this Last Quarter phase is on 15 July 2047 at 00:09 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 ∠2° of ♈ Aries tropical zodiac sector and will enter ♉ Taurus later.

Sturgeon Moon after 21 days

Next Full Moon is the Sturgeon Moon of August 2047 after 21 days on 5 August 2047 at 20:38.

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 6.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1769" and ∠1888".

Lunation 587 / 1540

The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 587 of Meeus index or 1540 from Brown series.

Synodic month length 29.51 days

The length of this lunation is 29 days, 12 hours and 13 minutes and it is 1 hour and 46 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 31 minutes shorter than the mean synodic month length. It is 5 hours and 38 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠240°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠240° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠274.9°.

Moon before apogee

11 days since point of perigee on 4 July 2047 at 04:56 in ♏ Scorpio the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next day until the Moon reaches the point of next apogee on 16 July 2047 at 03:57 in ♉ Taurus.

Distance to Moon 405 213 km

The Moon is 405 213 km (251 788 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 404 370 km (251 264 mi).

Moon before descending node

8 days after ascending node on 7 July 2047 at 11:43 in ♑ Capricorn the Moon is positioned north of the ecliptic over the following 6 days until the lunar crosses the ecliptic again from North to South in descending node on 21 July 2047 at 20:52 in ♋ Cancer.

Moon before northern standstill

9 days since the last southern standstill on 5 July 2047 at 15:10 in ♐ Sagittarius when the Moon has reached South declination of ∠-25.343° the lunar orbit is extending northward over the next 4 days to face maximum declination of ∠25.339° at the point of next northern standstill on 19 July 2047 at 18:19 in ♊ Gemini.

Draconic month

8 days since the beginning of this draconic month in ♑ Capricorn the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 7 days

In 7 days on 22 July 2047 at 22:49 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.
