Waning Gibbous in Aquarius

Waning Gibbous on . The illuminated surface of the moon is 78% and getting smaller. The lunar cycle is 19 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.

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.

4 days after Full Moon

Previous main lunar phase is the Full Moon before 4 days on 21 May 2054 at 15:16.

Flower Moon before 4 days

Next Full Moon is the Strawberry Moon of June 2054 after 24 days on 20 June 2054 at 03:42.

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 ∠1772"

Lunar disc appears visually 6.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1772" and ∠1894".

Lunation 672 / 1625

The Moon is 19 days old and navigating from the middle to the last part of the current synodic month. This is lunation 672 of Meeus index or 1625 from Brown series.

Synodic month length 29.4 days

The length of this lunation is 29 days, 9 hours and 40 minutes and it is 1 hour and 46 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 shorter than mean

The length of the current synodic month is 3 hours and 4 minutes shorter than the mean synodic month length. It is 3 hours and 5 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠288.9°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠288.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠316.1°.

Moon before apogee

13 days since point of perigee on 13 May 2054 at 03:26 in ♌ Leo the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next day until the Moon reaches the point of next apogee on 28 May 2054 at 00:43 in ♒ Aquarius.

Distance to Moon 404 580 km

The Moon is 404 580 km (251 394 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 404 285 km (251 211 mi).

Moon before descending node

11 days after ascending node on 15 May 2054 at 06:44 in ♍ Virgo the Moon is positioned north of the ecliptic over the following 2 days until the lunar crosses the ecliptic again from North to South in descending node on 29 May 2054 at 02:37 in ♓ Pisces.

Moon after southern standstill

2 days since the last southern standstill on 24 May 2054 at 11:01 in ♑ Capricorn when the Moon has reached South declination of ∠-19.115° the lunar orbit is extending northward over the next 12 days to face maximum declination of ∠19.164° at the point of next northern standstill on 7 June 2054 at 14:08 in ♊ Gemini.

Draconic month

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

Syzygy in 10 days

In 10 days on 6 June 2054 at 02:40 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.
