Waning Gibbous in Aquarius

Waning Gibbous on . Illuminated surface of the Moon is 65% and getting smaller. Lunar cycle is 20 days old.

Moonrise and moonset

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.

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon is entering ♒ Aquarius

Moon is passing first ∠0° of ♒ Aquarius tropical zodiac sector.

5 days after Full Moon

Previous main lunar phase is the Full Moon before 5 days on 1 June 2091 at 17:31.

Strawberry Moon before 5 days

Next Full Moon is the Buck Moon of July 2091 after 23 days on 1 July 2091 at 01:54.

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 ∠1810"

Lunar disc appears visually 4.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1810" and ∠1890".

Lunation 1130 / 2083

The Moon is 20 days old and navigating from the middle to the last part of the current synodic month. This is lunation 1130 of Meeus index or 2083 from Brown series.

Synodic month length 29.57 days

The length of this lunation is 29 days, 13 hours and 34 minutes and it is 1 hour and 59 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 50 minutes longer than the mean synodic month length. It is 6 hours and 13 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠214.7°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠214.7° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠245.7°.

Moon before apogee

7 days since point of perigee on 30 May 2091 at 19:30 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 4 days until the Moon reaches the point of next apogee on 11 June 2091 at 19:05 in ♈ Aries.

Distance to Moon 395 978 km

The Moon is 395 978 km (246 049 mi) away from Earth and getting further over the next 4 days until the point apogee when Earth-Moon distance is going to be 404 966 km (251 634 mi).

Moon in descending node

Moon is in descending node in ♒ Aquarius at 23:53 crossing the ecliptic from North to South. Lunar position remains south of if for the upcoming 14 days until Moon's next ascending node later on 22 June 2091 at 07:10 in ♍ Virgo.

Moon after southern standstill

4 days since the last southern standstill on 3 June 2091 at 09:48 in ♑ Capricorn when the Moon has reached South declination of ∠-18.930° the lunar orbit is extending northward over the next 10 days to face maximum declination of ∠18.975° at the point of next northern standstill on 17 June 2091 at 21:16 in ♊ Gemini.

Draconic month

12 days since the beginning of this draconic month in ♍ Virgo the Moon is navigating from the middle to the last part of the lunar cycle.

Syzygy in 9 days

In 9 days on 17 June 2091 at 02:41 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.
