Last Quarter in Aries

Last Quarter on . The illuminated surface of the moon is 54% and getting smaller. The lunar cycle is 21 days old.

* The exact date and time of this Last Quarter phase is on 17 July 2082 at 22:58 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 ∠20° of ♈ Aries tropical zodiac sector.

Sturgeon Moon after 22 days

Next Full Moon is the Sturgeon Moon of August 2082 after 22 days on 8 August 2082 at 14:33.

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 ∠1768"

Lunar disc appears visually 6.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1888".

Lunation 1020 / 1973

The Moon is 21 days old and navigating through the last part of the current synodic month. This is lunation 1020 of Meeus index or 1973 from Brown series.

Synodic month length 29.44 days

The length of this lunation is 29 days, 10 hours and 38 minutes and it is 1 hour and 14 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 6 minutes shorter than the mean synodic month length. It is 4 hours and 3 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠265.3°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠265.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠298.1°.

Moon at apogee

Moon is at apogee at 16:24 about 12 days since last perigee on 4 July 2082 at 20:11 in ♎ Libra the lunar orbit is going to narrow while the Moon is moving towards the Earth over the upcoming 12 days until point of next perigee on 29 July 2082 at 23:55 in ♍ Virgo.

Distance to Moon 404 169 km

This apogee Moon is 404 169 km (251 139 mi) away from Earth. This is the year's closest apogee of 2082. It is 1 239 km further than the mean apogee distance, but it is still 118 km closer than the farthest apogee of 21st century.

Moon after ascending node

4 days after ascending node on 13 July 2082 at 02:53 in ♒ Aquarius the Moon is positioned north of the ecliptic over the following 9 days until the lunar crosses the ecliptic again from North to South in descending node on 27 July 2082 at 09:04 in ♌ Leo.

Moon before northern standstill

9 days since the last southern standstill on 8 July 2082 at 10:27 in ♐ Sagittarius when the Moon has reached South declination of ∠-27.861° the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠27.898° at the point of next northern standstill on 22 July 2082 at 18:54 in ♊ Gemini.

Draconic month

4 days since the beginning of this draconic month in ♒ Aquarius the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 8 days

In 8 days on 25 July 2082 at 15:54 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.
