Waning Gibbous in Aquarius

Waning Gibbous on . The illuminated surface of the moon is 71% and getting smaller. The lunar cycle is 20 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.

Moon phase and lunation details

Moon in ♒ Aquarius

Moon is passing about ∠12° of ♒ Aquarius tropical zodiac sector.

5 days after Full Moon

Previous main lunar phase is the Full Moon before 5 days on 21 May 2016 at 21:15.

Flower Moon before 5 days

Next Full Moon is the Strawberry Moon of June 2016 after 23 days on 20 June 2016 at 11:02.

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 ∠1889"

Lunar disc appears visually 0.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1889" and ∠1893".

Lunation 202 / 1155

The Moon is 20 days old and navigating from the middle to the last part of the current synodic month. This is lunation 202 of Meeus index or 1155 from Brown series.

Synodic month length 29.31 days

The length of this lunation is 29 days, 7 hours and 30 minutes and it is 31 minutes shorter than the upcoming lunation's length. This is the year's shortest synodic month of 2016. 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 14 minutes shorter than the mean synodic month length. It is 55 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠10.8°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠10.8° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠27.6°.

Moon before perigee

8 days since point of apogee on 18 May 2016 at 22:06 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 3 June 2016 at 10:55 in ♉ Taurus.

Distance to Moon 379 547 km

The Moon is 379 547 km (235 840 mi) away from Earth and getting closer over the next 6 days until the point perigee when Earth-Moon distance is going to be 361 142 km (224 403 mi).

Moon before descending node

11 days after ascending node on 15 May 2016 at 20:39 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 30 May 2016 at 04:45 in ♓ Pisces.

Moon after southern standstill

3 days since the last southern standstill on 24 May 2016 at 11:16 in ♑ Capricorn when the Moon has reached South declination of ∠-18.539° the lunar orbit is extending northward over the next 9 days to face maximum declination of ∠18.575° at the point of next northern standstill on 6 June 2016 at 09:13 in ♋ Cancer.

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 8 days

In 8 days on 5 June 2016 at 03:00 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.
