Waning Gibbous in Gemini

Waning Gibbous on . The illuminated surface of the moon is 59% and getting smaller. The lunar cycle is 21 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 ♊ Gemini

Moon is passing about ∠6° of ♊ Gemini tropical zodiac sector.

6 days after Full Moon

Previous main lunar phase is the Full Moon before 6 days on 1 September 2088 at 02:57.

Harvest Moon before 6 days

Next Full Moon is the Harvest Moon of September 2088 after 23 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 ∠1963"

Lunar disc appears visually 3% wider than solar disc. Moon and Sun apparent angular diameters are ∠1963" and ∠1905".

Lunation 1096 / 2049

The Moon is 21 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

12 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 3 days until the Moon reaches the point of next perigee on 10 September 2088 at 15:52 in ♋ Cancer.

Distance to Moon 365 220 km

The Moon is 365 220 km (226 937 mi) away from Earth and getting closer over the next 3 days until the point perigee when Earth-Moon distance is going to be 368 469 km (228 956 mi).

Moon after descending node

2 days after descending node on 4 September 2088 at 19:26 in ♈ Aries the Moon is positioned south of the ecliptic over the following 10 days until the lunar crosses the ecliptic again from South to North in ascending node on 17 September 2088 at 16:44 in ♎ Libra.

Moon before northern standstill

12 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 day 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

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

Syzygy in 7 days

In 7 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.
