Waning Gibbous in Aries

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 ♈ Aries

Moon is passing about ∠11° of ♈ Aries tropical zodiac sector.

2 days after Full Moon

Previous main lunar phase is the Full Moon before 2 days on 1 September 2088 at 02:57.

Harvest Moon before 2 days

Next Full Moon is the Harvest Moon of September 2088 after 27 days on 30 September 2088 at 15:25.

Neap tide

There is low ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at big angle, so their combined tidal force is weak.

Apparent angular diameter ∠1887"

Lunar disc appears visually 0.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1887" and ∠1903".

Lunation 1096 / 2049

The Moon is 17 days old and navigating from the middle to the last part of the current synodic month. This is lunation 1096 of Meeus index or 2049 from Brown series.

Synodic month length 29.4 days

The length of this lunation is 29 days, 9 hours and 42 minutes and it is 3 hours shorter 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 shorter than mean

The length of the current synodic month is 3 hours and 2 minutes shorter than the mean synodic month length. It is 3 hours and 7 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠37.4°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠37.4° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠62.5°.

Moon before perigee

8 days since point of apogee on 26 August 2088 at 05:20 in ♐ Sagittarius the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 7 days until the Moon reaches the point of next perigee on 10 September 2088 at 15:52 in ♋ Cancer.

Distance to Moon 379 936 km

The Moon is 379 936 km (236 081 mi) away from Earth and getting closer over the next 7 days until the point perigee when Earth-Moon distance is going to be 368 469 km (228 956 mi).

Moon before descending node

13 days after ascending node on 21 August 2088 at 10:34 in ♎ Libra 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 4 September 2088 at 19:26 in ♈ Aries.

Moon before northern standstill

8 days since the last southern standstill on 25 August 2088 at 20:40 in ♐ Sagittarius when the Moon has reached South declination of ∠-19.084° the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠18.985° at the point of next northern standstill on 8 September 2088 at 17:54 in ♊ Gemini.

Draconic month

13 days since the beginning of this draconic month in ♎ Libra the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 11 days

In 11 days on 15 September 2088 at 01:58 in ♍ Virgo 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.
