Full Moon in Aquarius

Full Moon on . The illuminated surface of the moon is 99%. The lunar cycle is 15 days old.

* The exact date and time of this Full Moon phase is on 7 August 2017 at 18:11 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 in ♒ Aquarius

Moon is passing about ∠25° of ♒ Aquarius tropical zodiac sector.

It is Sturgeon Moon

The Full Moon these days is the Sturgeon of August 2017.

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 ∠1827"

Lunar disc appears visually 3.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1827" and ∠1893".

Lunation 217 / 1170

The Moon is 15 days old and navigating through the middle part of the current synodic month. This is lunation 217 of Meeus index or 1170 from Brown series.

Synodic month length 29.36 days

The length of this lunation is 29 days, 8 hours and 45 minutes and it is 2 hours and 15 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 shorter than mean

The length of the current synodic month is 3 hours and 59 minutes shorter than the mean synodic month length. It is 2 hours and 10 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠27.9°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠27.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠49.5°.

Moon after apogee

5 days since point of apogee on 2 August 2017 at 17:55 in ♐ Sagittarius the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 10 days until the Moon reaches the point of next perigee on 18 August 2017 at 13:14 in ♋ Cancer.

Distance to Moon 392 331 km

The Moon is 392 331 km (243 783 mi) away from Earth and getting closer over the next 10 days until the point perigee when Earth-Moon distance is going to be 366 129 km (227 502 mi).

Moon in descending node

Moon is in descending node in ♒ Aquarius at 10:56 crossing the ecliptic from North to South. Lunar position remains south of if for the upcoming 12 days until Moon's next ascending node later on 21 August 2017 at 10:34 in ♌ Leo.

Moon after southern standstill

3 days since the last southern standstill on 4 August 2017 at 18:17 in ♑ Capricorn when the Moon has reached South declination of ∠-19.393° the lunar orbit is extending northward over the next 9 days to face maximum declination of ∠19.381° at the point of next northern standstill on 18 August 2017 at 06:50 in ♋ Cancer.

Draconic month

14 days since the beginning of this draconic month in ♍ Virgo the Moon is navigating from the second to the final 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.
