Waning Gibbous in Aquarius

Waning Gibbous on . The illuminated surface of the moon is 65% and getting smaller. The lunar cycle is 20 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 ∠17° of ♒ Aquarius tropical zodiac sector.

5 days after Full Moon

Previous main lunar phase is the Full Moon before 5 days on 20 May 2065 at 02:05.

Flower Moon before 5 days

Next Full Moon is the Strawberry Moon of June 2065 after 23 days on 18 June 2065 at 09:28.

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 ∠1866"

Lunar disc appears visually 1.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1866" and ∠1894".

Lunation 808 / 1761

The Moon is 20 days old and navigating from the middle to the last part of the current synodic month. This is lunation 808 of Meeus index or 1761 from Brown series.

Synodic month length 29.65 days

The length of this lunation is 29 days, 15 hours and 34 minutes and it is 1 hour and 23 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 50 minutes longer than the mean synodic month length. It is 4 hours and 13 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠183°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠183° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠206.9°.

Moon after perigee

5 days since point of perigee on 19 May 2065 at 12:57 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 6 days until the Moon reaches the point of next apogee on 1 June 2065 at 09:08 in ♉ Taurus.

Distance to Moon 384 047 km

The Moon is 384 047 km (238 636 mi) away from Earth and getting further over the next 6 days until the point apogee when Earth-Moon distance is going to be 406 272 km (252 446 mi).

Moon after ascending node

1 day after ascending node on 24 May 2065 at 02:55 in ♑ Capricorn the Moon is positioned north of the ecliptic over the following 13 days until the lunar crosses the ecliptic again from North to South in descending node on 7 June 2065 at 16:41 in ♋ Cancer.

Moon after southern standstill

3 days since the last southern standstill on 21 May 2065 at 12:36 in ♐ Sagittarius when the Moon has reached South declination of ∠-26.190° the lunar orbit is extending northward over the next 10 days to face maximum declination of ∠26.155° at the point of next northern standstill on 4 June 2065 at 16:59 in ♊ Gemini.

Draconic month

1 day since the beginning of this draconic month in ♑ Capricorn the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 9 days

In 9 days on 4 June 2065 at 03:05 in ♊ Gemini 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.
