Last Quarter in Aquarius

Last Quarter on . The illuminated surface of the moon is 54% and getting smaller. The lunar cycle is 21 days old.

* The exact date and time of this Last Quarter phase is on 30 April 2081 at 21:24 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 ∠6° of ♒ Aquarius tropical zodiac sector.

Flower Moon after 22 days

Next Full Moon is the Flower Moon of May 2081 after 22 days on 22 May 2081 at 20:26.

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 6.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1778" and ∠1904".

Lunation 1005 / 1958

The Moon is 21 days old and navigating through the last part of the current synodic month. This is lunation 1005 of Meeus index or 1958 from Brown series.

Synodic month length 29.58 days

The length of this lunation is 29 days, 13 hours and 54 minutes and it is 3 hours and 1 minute 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 1 hour and 10 minutes longer than the mean synodic month length. It is 5 hours and 53 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠231.2°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠231.2° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠265.8°.

Moon before apogee

9 days since point of perigee on 20 April 2081 at 18:04 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 2 May 2081 at 14:12 in ♒ Aquarius.

Distance to Moon 403 042 km

The Moon is 403 042 km (250 439 mi) away from Earth and getting further over the next 2 days until the point apogee when Earth-Moon distance is going to be 404 484 km (251 335 mi).

Moon before ascending node

9 days after descending node on 20 April 2081 at 16:02 in ♍ Virgo the Moon is positioned south of the ecliptic over the following 3 days until the lunar crosses the ecliptic again from South to North in ascending node on 4 May 2081 at 10:34 in ♓ Pisces.

Moon after southern standstill

3 days since the last southern standstill on 27 April 2081 at 11:19 in ♐ Sagittarius when the Moon has reached South declination of ∠-28.521° the lunar orbit is extending northward over the next 11 days to face maximum declination of ∠28.437° at the point of next northern standstill on 11 May 2081 at 21:38 in ♊ Gemini.

Draconic month

23 days since the beginning of this draconic month in ♓ Pisces the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 8 days

In 8 days on 8 May 2081 at 22:09 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.
