Waning Gibbous in Aquarius

Waning Gibbous on . Illuminated surface of the Moon is 70% 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 in ♒ Aquarius

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

5 days after Full Moon

Previous main lunar phase is the Full Moon before 5 days on 18 May 2019 at 21:11.

Flower Moon before 5 days

Next Full Moon is the Strawberry Moon of June 2019 after 23 days on 17 June 2019 at 08:31.

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 ∠1776"

Lunar disc appears visually 6.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1776" and ∠1895".

Lunation 239 / 1192

The Moon is 20 days old and navigating from the middle to the last part of the current synodic month. This is lunation 239 of Meeus index or 1192 from Brown series.

Synodic month length 29.47 days

The length of this lunation is 29 days, 11 hours and 16 minutes and it is 2 hours and 2 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 1 hour and 28 minutes shorter than the mean synodic month length. It is 4 hours and 41 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠263°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠263° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠296.1°.

Moon before apogee

10 days since point of perigee on 13 May 2019 at 21:53 in ♍ Virgo the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 2 days until the Moon reaches the point of next apogee on 26 May 2019 at 13:27 in ♒ Aquarius.

Distance to Moon 403 508 km

The Moon is 403 508 km (250 728 mi) away from Earth and getting further over the next 2 days until the point apogee when Earth-Moon distance is going to be 404 134 km (251 117 mi).

Moon after descending node

1 day after descending node on 22 May 2019 at 19:12 in ♑ Capricorn the Moon is positioned south of the ecliptic over the following 12 days until the lunar crosses the ecliptic again from South to North in ascending node on 5 June 2019 at 22:46 in ♋ Cancer.

Moon after southern standstill

2 days since the last southern standstill on 22 May 2019 at 06:41 in ♑ Capricorn when the Moon has reached South declination of ∠-22.313° the lunar orbit is extending northward over the next 12 days to face maximum declination of ∠22.361° at the point of next northern standstill on 5 June 2019 at 12:58 in ♋ Cancer.

Draconic month

14 days since the beginning of this draconic month in ♋ Cancer the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 9 days

In 9 days on 3 June 2019 at 10:02 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.
