Waning Gibbous in Aquarius

Waning Gibbous on . Illuminated surface of the Moon is 79% and getting smaller. Lunar cycle is 19 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 ∠18° of ♒ Aquarius tropical zodiac sector.

4 days after Full Moon

Previous main lunar phase is the Full Moon before 4 days on 9 June 2017 at 13:10.

Strawberry Moon before 4 days

Next Full Moon is the Buck Moon of July 2017 after 24 days on 9 July 2017 at 04:07.

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 ∠1825"

Lunar disc appears visually 3.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1825" and ∠1889".

Lunation 215 / 1168

The Moon is 19 days old and navigating from the middle to the last part of the current synodic month. This is lunation 215 of Meeus index or 1168 from Brown series.

Synodic month length 29.28 days

The length of this lunation is 29 days, 6 hours and 46 minutes and it is 29 minutes shorter than the upcoming lunation's length. This is the year's shortest synodic month of 2017. 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 5 hours and 58 minutes shorter than the mean synodic month length. It is 11 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠356°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠356° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠11°.

Moon after apogee

5 days since point of apogee on 8 June 2017 at 22:21 in ♐ Sagittarius the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 8 days until the Moon reaches the point of next perigee on 23 June 2017 at 10:49 in ♊ Gemini.

Distance to Moon 392 646 km

The Moon is 392 646 km (243 979 mi) away from Earth and getting closer over the next 8 days until the point perigee when Earth-Moon distance is going to be 357 938 km (222 412 mi).

Moon before descending node

14 days after ascending node on 31 May 2017 at 11:56 in ♌ Leo the Moon is positioned north of the ecliptic over the following day until the lunar crosses the ecliptic again from North to South in descending node on 15 June 2017 at 02:40 in ♒ Aquarius.

Moon after southern standstill

3 days since the last southern standstill on 11 June 2017 at 03:36 in ♑ Capricorn when the Moon has reached South declination of ∠-19.428° the lunar orbit is extending northward over the next 9 days to face maximum declination of ∠19.434° at the point of next northern standstill on 24 June 2017 at 11:12 in ♋ Cancer.

Draconic month

14 days since the beginning of this draconic month in ♌ Leo the Moon is navigating from the first to the middle part of the lunar cycle.

Syzygy in 9 days

In 9 days on 24 June 2017 at 02:31 in ♋ Cancer 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.
