Last Quarter in Aquarius

Last Quarter on . The illuminated surface of the moon is 43% and getting smaller. The lunar cycle is 22 days old.

* The exact date and time of this Last Quarter phase is on 3 May 2021 at 19:50 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.

Flower Moon after 21 days

Next Full Moon is the Flower Moon of May 2021 after 21 days on 26 May 2021 at 11:14.

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 ∠1869"

Lunar disc appears visually 1.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1869" and ∠1902".

Lunation 263 / 1216

The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 263 of Meeus index or 1216 from Brown series.

Synodic month length 29.69 days

The length of this lunation is 29 days, 16 hours and 29 minutes and it is 36 minutes longer than the upcoming lunation's length. This is the year's longest synodic month of 2021. 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 3 hours and 45 minutes longer than the mean synodic month length. It is 3 hours and 18 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠154.8°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠154.8° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠178.9°.

Moon after perigee

6 days since point of perigee on 27 April 2021 at 15:24 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 7 days until the Moon reaches the point of next apogee on 11 May 2021 at 21:54 in ♉ Taurus.

Distance to Moon 383 444 km

The Moon is 383 444 km (238 261 mi) away from Earth and getting further over the next 7 days until the point apogee when Earth-Moon distance is going to be 406 512 km (252 595 mi).

Moon after descending node

5 days after descending node on 29 April 2021 at 09:18 in ♐ Sagittarius 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 13 May 2021 at 10:29 in ♊ Gemini.

Moon after southern standstill

3 days since the last southern standstill on 1 May 2021 at 09:37 in ♑ Capricorn when the Moon has reached South declination of ∠-25.591° the lunar orbit is extending northward over the next 11 days to face maximum declination of ∠25.640° at the point of next northern standstill on 15 May 2021 at 22:25 in ♋ Cancer.

Draconic month

18 days since the beginning of this draconic month in ♊ Gemini the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 7 days

In 7 days on 11 May 2021 at 19:00 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.
