Last Quarter in Aries

Last Quarter on . The illuminated surface of the moon is 50% and getting smaller. The lunar cycle is 22 days old.

* The exact date and time of this Last Quarter phase is on 24 June 2038 at 12:39 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 is entering ♈ Aries

Moon is passing first ∠3° of ♈ Aries tropical zodiac sector.

Buck Moon after 21 days

Next Full Moon is the Buck Moon of July 2038 after 21 days on 16 July 2038 at 11:48.

Moderate tide

There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.

Apparent angular diameter ∠1778"

Lunar disc appears visually 6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1778" and ∠1888".

Lunation 475 / 1428

The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 475 of Meeus index or 1428 from Brown series.

Synodic month length 29.55 days

The length of this lunation is 29 days, 13 hours and 8 minutes and it is 2 hours 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 longer than mean

The length of the current synodic month is 24 minutes longer than the mean synodic month length. It is 6 hours and 39 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠226°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠226° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠259.5°.

Moon before apogee

9 days since point of perigee on 14 June 2038 at 15:26 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 2 days until the Moon reaches the point of next apogee on 26 June 2038 at 12:55 in ♈ Aries.

Distance to Moon 403 103 km

The Moon is 403 103 km (250 477 mi) away from Earth and getting further over the next 2 days until the point apogee when Earth-Moon distance is going to be 404 680 km (251 456 mi).

Moon after descending node

6 days after descending node on 18 June 2038 at 02:42 in ♑ Capricorn 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 2 July 2038 at 12:47 in ♋ Cancer.

Moon after southern standstill

6 days since the last southern standstill on 18 June 2038 at 05:58 in ♑ Capricorn when the Moon has reached South declination of ∠-23.039° the lunar orbit is extending northward over the next 8 days to face maximum declination of ∠23.041° at the point of next northern standstill on 2 July 2038 at 16:20 in ♋ Cancer.

Draconic month

19 days since the beginning of this draconic month in ♋ Cancer the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 8 days

In 8 days on 2 July 2038 at 13:32 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.
