Last Quarter in Aquarius

Last Quarter on . The illuminated surface of the moon is 46% and getting smaller. The lunar cycle is 22 days old.

* The exact date and time of this Last Quarter phase is on 17 April 2066 at 02:23 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 ♒ Aquarius

Moon is passing first ∠3° of ♒ Aquarius tropical zodiac sector.

Flower Moon after 22 days

Next Full Moon is the Flower Moon of May 2066 after 22 days on 9 May 2066 at 18:58.

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 ∠1947"

Lunar disc appears visually 1.9% wider than solar disc. Moon and Sun apparent angular diameters are ∠1947" and ∠1911".

Lunation 819 / 1772

The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 819 of Meeus index or 1772 from Brown series.

Synodic month length 29.59 days

The length of this lunation is 29 days, 14 hours and 16 minutes and it is 53 minutes shorter than the upcoming lunation's length. The lengths of the following synodic months are going to increase with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).

Lunation length longer than mean

The length of the current synodic month is 1 hour and 32 minutes longer than the mean synodic month length. It is 5 hours and 31 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠96.6°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠96.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠132.1°.

Moon after perigee

4 days since point of perigee on 12 April 2066 at 22:32 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 11 days until the Moon reaches the point of next apogee on 28 April 2066 at 19:52 in ♊ Gemini.

Distance to Moon 368 151 km

The Moon is 368 151 km (228 758 mi) away from Earth and getting further over the next 11 days until the point apogee when Earth-Moon distance is going to be 405 408 km (251 909 mi).

Moon after ascending node

1 day after ascending node on 16 April 2066 at 00:07 in ♑ Capricorn the Moon is positioned north of the ecliptic over the following 12 days until the lunar crosses the ecliptic again from North to South in descending node on 30 April 2066 at 00:48 in ♋ Cancer.

Moon after southern standstill

3 days since the last southern standstill on 14 April 2066 at 10:46 in ♐ Sagittarius when the Moon has reached South declination of ∠-24.901° the lunar orbit is extending northward over the next 10 days to face maximum declination of ∠24.799° at the point of next northern standstill on 28 April 2066 at 05:54 in ♊ Gemini.

Draconic month

1 day 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 24 April 2066 at 12:29 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.
