Waning Gibbous in Sagittarius

Waning Gibbous on . Illuminated surface of the Moon is 97% and getting smaller. Lunar cycle is 16 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 ♐ Sagittarius

Moon is passing about ∠19° of ♐ Sagittarius tropical zodiac sector.

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 18 May 2019 at 21:11.

Flower Moon before 1 day

Next Full Moon is the Strawberry Moon of June 2019 after 27 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 ∠1841"

Lunar disc appears visually 2.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1841" and ∠1896".

Lunation 239 / 1192

The Moon is 16 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

6 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 6 days until the Moon reaches the point of next apogee on 26 May 2019 at 13:27 in ♒ Aquarius.

Distance to Moon 389 357 km

The Moon is 389 357 km (241 935 mi) away from Earth and getting further over the next 6 days until the point apogee when Earth-Moon distance is going to be 404 134 km (251 117 mi).

Moon before descending node

10 days after ascending node on 9 May 2019 at 18:50 in ♋ Cancer 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 22 May 2019 at 19:12 in ♑ Capricorn.

Moon before southern standstill

11 days since the last northern standstill on 9 May 2019 at 05:46 in ♋ Cancer when the Moon has reached North declination of ∠22.243° the lunar orbit is extending southward over the next day to face maximum declination of ∠-22.313° at the point of next southern standstill on 22 May 2019 at 06:41 in ♑ Capricorn.

Draconic month

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

Syzygy in 13 days

In 13 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.
