Waning Gibbous in Aquarius

Waning Gibbous on . Illuminated surface of the Moon is 86% and getting smaller. Lunar cycle is 18 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 ∠1° of ♒ Aquarius tropical zodiac sector.

3 days after Full Moon

Previous main lunar phase is the Full Moon before 3 days on 3 June 2042 at 20:48.

Strawberry Moon before 3 days

Next Full Moon is the Buck Moon of July 2042 after 25 days on 3 July 2042 at 08:09.

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 ∠1907"

Lunar disc appears visually 0.9% wider than solar disc. Moon and Sun apparent angular diameters are ∠1907" and ∠1890".

Lunation 524 / 1477

The Moon is 18 days old and navigating from the middle to the last part of the current synodic month. This is lunation 524 of Meeus index or 1477 from Brown series.

Synodic month length 29.37 days

The length of this lunation is 29 days, 8 hours and 53 minutes and it is 1 hour and 11 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 51 minutes shorter than the mean synodic month length. It is 2 hours and 18 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠33.6°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠33.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠57.3°.

Moon before perigee

9 days since point of apogee on 29 May 2042 at 07:12 in ♎ Libra the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 6 days until the Moon reaches the point of next perigee on 13 June 2042 at 22:24 in ♈ Aries.

Distance to Moon 375 941 km

The Moon is 375 941 km (233 599 mi) away from Earth and getting closer over the next 6 days until the point perigee when Earth-Moon distance is going to be 367 563 km (228 393 mi).

Moon before ascending node

7 days after descending node on 31 May 2042 at 00:41 in ♏ Scorpio the Moon is positioned south of the ecliptic over the following 6 days until the lunar crosses the ecliptic again from South to North in ascending node on 13 June 2042 at 12:16 in ♈ Aries.

Moon after southern standstill

2 days since the last southern standstill on 5 June 2042 at 11:37 in ♑ Capricorn when the Moon has reached South declination of ∠-28.094° the lunar orbit is extending northward over the next 10 days to face maximum declination of ∠28.070° at the point of next northern standstill on 18 June 2042 at 08:35 in ♋ Cancer.

Draconic month

21 days since the beginning of this draconic month in ♈ Aries the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 10 days

In 10 days on 17 June 2042 at 19:48 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.
