Full Moon in Aquarius

Full Moon on . The illuminated surface of the moon is 100%. The lunar cycle is 14 days old.

* The exact date and time of this Full Moon phase is on 3 August 2031 at 01:45 UTC.

Moonrise and moonset

The moon rises at sunset and sets at sunrise. It is visible all night and it is high in the sky around midnight.

Moon phase and lunation details

Moon is entering ♒ Aquarius

Moon is passing first ∠2° of ♒ Aquarius tropical zodiac sector.

It is Sturgeon Moon

The Full Moon these days is the Sturgeon of August 2031.

Spring tide

There is high Full Moon ocean tide on this date. Combined Sun and Moon gravitational tidal force working on Earth is strong, because of the Sun-Earth-Moon syzygy alignment.

Apparent angular diameter ∠1970"

Lunar disc appears visually 4.1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1970" and ∠1891".

Lunation 390 / 1343

The Moon is 14 days old and navigating through the middle part of the current synodic month. This is lunation 390 of Meeus index or 1343 from Brown series.

Synodic month length 29.62 days

The length of this lunation is 29 days, 14 hours and 52 minutes and it is 37 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 8 minutes longer than the mean synodic month length. It is 4 hours and 55 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠188.7°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠188.7° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠213.5°.

Moon at perigee

Moon is at perigee at 06:47 about 14 days since last apogee on 18 July 2031 at 14:28 in ♋ Cancer the lunar orbit is going to widen while the Moon is moving away from the Earth over the upcoming 12 days until point of next apogee on 14 August 2031 at 21:37 in ♋ Cancer.

Distance to Moon 358 060 km

This perigee Moon is 358 060 km (222 488 mi) away from Earth. It is 4 448 km closer than the mean perigee distance, but it is still 12 296 km further than the closest perigee of 21st century.

Moon after ascending node

4 days after ascending node on 28 July 2031 at 23:54 in ♏ Scorpio the Moon is positioned north of the ecliptic over the following 8 days until the lunar crosses the ecliptic again from North to South in descending node on 10 August 2031 at 14:10 in ♉ Taurus.

Moon after southern standstill

2 days since the last southern standstill on 30 July 2031 at 15:45 in ♐ Sagittarius when the Moon has reached South declination of ∠-20.951° the lunar orbit is extending northward over the next 10 days to face maximum declination of ∠20.868° at the point of next northern standstill on 12 August 2031 at 15:58 in ♊ Gemini.

Draconic month

4 days since the beginning of this draconic month in ♏ Scorpio the Moon is navigating from the beginning to the first part of the lunar cycle.

Sun-Earth-Moon syzygy

The Moon is in a Full Moon geocentric opposition with the Sun and thus forming Sun-Earth-Moon syzygy alignment.
