Waning Gibbous in Aquarius

Waning Gibbous on . The illuminated surface of the moon is 95% and getting smaller. The lunar cycle is 16 days old.

Moonrise and moonset

The moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.

Moon phase and lunation details

Moon in ♒ Aquarius

Moon is passing about ∠9° of ♒ Aquarius tropical zodiac sector.

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 4 July 2031 at 19:01.

Buck Moon before 1 day

Next Full Moon is the Sturgeon Moon of August 2031 after 27 days on 3 August 2031 at 01:45.

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 ∠1965"

Lunar disc appears visually 4% wider than solar disc. Moon and Sun apparent angular diameters are ∠1965" and ∠1887".

Lunation 389 / 1342

The Moon is 16 days old and navigating from the middle to the last part of the current synodic month. This is lunation 389 of Meeus index or 1342 from Brown series.

Synodic month length 29.64 days

The length of this lunation is 29 days, 15 hours and 16 minutes and it is 24 minutes longer than the upcoming lunation's length. This is the year's longest synodic month of 2031. 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 31 minutes longer than the mean synodic month length. It is 4 hours and 31 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠165.9°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠165.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠188.7°.

Moon after perigee

1 day since point of perigee on 4 July 2031 at 21:14 in ♑ Capricorn the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 12 days until the Moon reaches the point of next apogee on 18 July 2031 at 14:28 in ♋ Cancer.

Distance to Moon 364 763 km

The Moon is 364 763 km (226 653 mi) away from Earth and getting further over the next 12 days until the point apogee when Earth-Moon distance is going to be 406 535 km (252 609 mi).

Moon after ascending node

4 days after ascending node on 1 July 2031 at 18:35 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 14 July 2031 at 12:38 in ♉ Taurus.

Moon after southern standstill

3 days since the last southern standstill on 3 July 2031 at 05:15 in ♐ Sagittarius when the Moon has reached South declination of ∠-21.077° the lunar orbit is extending northward over the next 9 days to face maximum declination of ∠21.045° at the point of next northern standstill on 16 July 2031 at 09:01 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.

Syzygy in 13 days

In 13 days on 19 July 2031 at 13:40 in ♋ Cancer 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.
