Waning Gibbous in Aquarius

Waning Gibbous on . The illuminated surface of the moon is 94% and getting smaller. The lunar cycle is 17 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.

12603 days after

Previous main lunar phase is the before 12603 days on at :.

Moon before 12603 days

Next Full Moon is the Moon of after 1 day on at :.

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 ∠1944"

Lunar disc appears visually 3% wider than solar disc. Moon and Sun apparent angular diameters are ∠1944" and ∠1887".

Lunation -953 /

The Moon is 17 days old and navigating from the middle to the last part of the current synodic month. This is lunation -953 of Meeus index or from Brown series.

Synodic month length 0 days

The length of this lunation is days, 1 hour and 1 minute and it is longer than the upcoming lunation's length. 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 same as the mean

The length of the current synodic month is equal to the mean synodic month length. It is %hours_to_shortest% and %minutes_to_shortest% longer than the 21st century's shortest and %hours_to_longest% and %minutes_to_longest% shorter than the 21st century's longest synodic months.

Lunar orbit details for

True anomaly ∠0°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠0° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠0°.

Moon before perigee

12603 days since point of apogee on at : in &#; the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next day until the Moon reaches the point of next perigee on at : in &#; .

Distance to Moon 368 721 km

The Moon is 368 721 km (229 113 mi) away from Earth and getting closer over the next day until the point perigee when Earth-Moon distance is going to be 0 km (0 mi).

Moon before descending node

12603 days after descending node on at : in &#; the Moon is positioned south of the ecliptic over the following day until the lunar crosses the ecliptic again from South to North in ascending node on at : in &#; .

Moon before northern standstill

12603 days since the last southern standstill on at : in &#; when the Moon has reached South declination of ∠° the lunar orbit is extending northward over the next day to face maximum declination of ∠° at the point of next northern standstill on at : in &#; .

Draconic month

12603 days since the beginning of this draconic month in &#; the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 1 day

In 1 day on at : in &#; the Moon is going to be in a geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
