Last Quarter in Aquarius

Last Quarter on . The illuminated surface of the moon is 49% and getting smaller. The lunar cycle is 22 days old.

* The exact date and time of this Last Quarter phase is on 10 May 2091 at 08:36 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 ♒ Aquarius

Moon is passing about ∠22° of ♒ Aquarius tropical zodiac sector.

Strawberry Moon after 22 days

Next Full Moon is the Strawberry Moon of June 2091 after 22 days on 1 June 2091 at 17:31.

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 ∠1818"

Lunar disc appears visually 4.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1818" and ∠1900".

Lunation 1129 / 2082

The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 1129 of Meeus index or 2082 from Brown series.

Synodic month length 29.66 days

The length of this lunation is 29 days, 15 hours and 47 minutes and it is 2 hours and 13 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 3 hours and 3 minutes longer than the mean synodic month length. It is 4 hours shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠189.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠189.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠214.7°.

Moon before apogee

7 days since point of perigee on 2 May 2091 at 14:03 in ♎ Libra the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 4 days until the Moon reaches the point of next apogee on 15 May 2091 at 03:48 in ♈ Aries.

Distance to Moon 394 346 km

The Moon is 394 346 km (245 035 mi) away from Earth and getting further over the next 4 days until the point apogee when Earth-Moon distance is going to be 405 973 km (252 260 mi).

Moon before descending node

11 days after ascending node on 29 April 2091 at 04:04 in ♍ Virgo the Moon is positioned north of the ecliptic over the following day until the lunar crosses the ecliptic again from North to South in descending node on 11 May 2091 at 22:03 in ♓ Pisces.

Moon after southern standstill

3 days since the last southern standstill on 6 May 2091 at 22:47 in ♐ Sagittarius when the Moon has reached South declination of ∠-18.782° the lunar orbit is extending northward over the next 11 days to face maximum declination of ∠18.883° at the point of next northern standstill on 21 May 2091 at 13:53 in ♊ Gemini.

Draconic month

11 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 18 May 2091 at 13:07 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.
