Last Quarter in Aquarius

Last Quarter on . Illuminated surface of the Moon is 52% and getting smaller. Lunar cycle is 22 days old.

* The exact date and time of this Last Quarter phase is on 21 April 2090 at 15:50 UTC.

Moonrise and moonset

Moon rises at midnight and sets at noon. It is visible to the south in the morning.

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon is entering ♒ Aquarius

Moon is passing first ∠0° of ♒ Aquarius tropical zodiac sector.

Flower Moon after 22 days

Next Full Moon is the Flower Moon of May 2090 after 22 days on 13 May 2090 at 19:01.

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 ∠1789"

Lunar disc appears visually 6.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1789" and ∠1909".

Lunation 1116 / 2069

The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 1116 of Meeus index or 2069 from Brown series.

Synodic month length 29.64 days

The length of this lunation is 29 days, 15 hours and 24 minutes and it is 3 hours and 7 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 longer than mean

The length of the current synodic month is 2 hours and 40 minutes longer than the mean synodic month length. It is 4 hours and 23 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠214.3°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠214.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠246°.

Moon before apogee

8 days since point of perigee on 12 April 2090 at 12:39 in ♍ Virgo 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 24 April 2090 at 10:58 in ♓ Pisces.

Distance to Moon 400 556 km

The Moon is 400 556 km (248 894 mi) away from Earth and getting further over the next 2 days until the point apogee when Earth-Moon distance is going to be 405 000 km (251 655 mi).

Moon before descending node

8 days after ascending node on 12 April 2090 at 16:39 in ♍ Virgo the Moon is positioned north of the ecliptic over the following 5 days until the lunar crosses the ecliptic again from North to South in descending node on 26 April 2090 at 12:13 in ♓ Pisces.

Moon after southern standstill

2 days since the last southern standstill on 19 April 2090 at 02:47 in ♑ Capricorn when the Moon has reached South declination of ∠-18.213° the lunar orbit is extending northward over the next 12 days to face maximum declination of ∠18.290° at the point of next northern standstill on 3 May 2090 at 15:57 in ♊ Gemini.

Draconic month

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

Syzygy in 8 days

In 8 days on 29 April 2090 at 19:12 in ♉ Taurus 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.
