Waning Gibbous in Aquarius

Waning Gibbous on . The illuminated surface of the moon is 99% and getting smaller. The lunar cycle is 15 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 ∠21° of ♒ Aquarius tropical zodiac sector.

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 30 July 2091 at 12:01.

Buck Moon before 1 day

Next Full Moon is the Sturgeon Moon of August 2091 after 28 days on 29 August 2091 at 00:39.

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 ∠1834"

Lunar disc appears visually 3.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1834" and ∠1890".

Lunation 1132 / 2085

The Moon is 15 days old and navigating from the middle to the last part of the current synodic month. This is lunation 1132 of Meeus index or 2085 from Brown series.

Synodic month length 29.42 days

The length of this lunation is 29 days, 10 hours and 6 minutes and it is 53 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 2 hours and 38 minutes shorter than the mean synodic month length. It is 3 hours and 31 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠280.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠280.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠310.2°.

Moon before apogee

8 days since point of perigee on 23 July 2091 at 04:02 in ♎ Libra the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 5 days until the Moon reaches the point of next apogee on 6 August 2091 at 07:42 in ♉ Taurus.

Distance to Moon 390 916 km

The Moon is 390 916 km (242 904 mi) away from Earth and getting further over the next 5 days until the point apogee when Earth-Moon distance is going to be 404 324 km (251 235 mi).

Moon before descending node

12 days after ascending node on 19 July 2091 at 10:20 in ♍ Virgo 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 1 August 2091 at 10:40 in ♓ Pisces.

Moon after southern standstill

3 days since the last southern standstill on 28 July 2091 at 05:06 in ♑ Capricorn when the Moon has reached South declination of ∠-18.921° the lunar orbit is extending northward over the next 11 days to face maximum declination of ∠18.890° at the point of next northern standstill on 11 August 2091 at 15:21 in ♋ Cancer.

Draconic month

12 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 14 days

In 14 days on 15 August 2091 at 00:22 in ♌ Leo 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.
