Last Quarter in Aries

Last Quarter on . The illuminated surface of the moon is 52% and getting smaller. The lunar cycle is 22 days old.

* The exact date and time of this Last Quarter phase is on 8 July 2091 at 17:21 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 ∠14° of ♈ Aries tropical zodiac sector.

Buck Moon after 22 days

Next Full Moon is the Buck Moon of July 2091 after 22 days on 30 July 2091 at 12:01.

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 ∠1770"

Lunar disc appears visually 6.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1770" and ∠1887".

Lunation 1131 / 2084

The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 1131 of Meeus index or 2084 from Brown series.

Synodic month length 29.48 days

The length of this lunation is 29 days, 11 hours and 35 minutes and it is 1 hour and 29 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 1 hour and 9 minutes shorter than the mean synodic month length. It is 5 hours longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠245.7°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠245.7° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠280.5°.

Moon before apogee

11 days since point of perigee on 27 June 2091 at 11:38 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 9 July 2091 at 13:01 in ♈ Aries.

Distance to Moon 404 916 km

The Moon is 404 916 km (251 603 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 404 243 km (251 185 mi).

Moon after descending node

3 days after descending node on 5 July 2091 at 03:56 in ♓ Pisces the Moon is positioned south of the ecliptic over the following 10 days until the lunar crosses the ecliptic again from South to North in ascending node on 19 July 2091 at 10:20 in ♍ Virgo.

Moon before northern standstill

7 days since the last southern standstill on 30 June 2091 at 20:26 in ♐ Sagittarius when the Moon has reached South declination of ∠-18.969° the lunar orbit is extending northward over the next 6 days to face maximum declination of ∠18.955° at the point of next northern standstill on 15 July 2091 at 05:57 in ♋ Cancer.

Draconic month

16 days since the beginning of this draconic month in ♍ Virgo the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 8 days

In 8 days on 16 July 2091 at 14:15 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.
