Waning Gibbous in Gemini

Waning Gibbous on . The illuminated surface of the moon is 60% 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 ∠23° of ♊ Gemini tropical zodiac sector.

5 days after Full Moon

Previous main lunar phase is the Full Moon before 5 days on 21 September 2078 at 17:31.

Harvest Moon before 5 days

Next Full Moon is the Hunter Moon of October 2078 after 23 days on 21 October 2078 at 02:55.

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 ∠1953"

Lunar disc appears visually 2% wider than solar disc. Moon and Sun apparent angular diameters are ∠1953" and ∠1915".

Lunation 973 / 1926

The Moon is 21 days old and navigating from the middle to the last part of the current synodic month. This is lunation 973 of Meeus index or 1926 from Brown series.

Synodic month length 29.63 days

The length of this lunation is 29 days, 15 hours and 7 minutes and it is 2 hours and 43 minutes 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 longer than mean

The length of the current synodic month is 2 hours and 23 minutes longer than the mean synodic month length. It is 4 hours and 40 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠115.1°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠115.1° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠146.4°.

Moon after perigee

3 days since point of perigee on 23 September 2078 at 13:38 in ♈ Aries the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 11 days until the Moon reaches the point of next apogee on 9 October 2078 at 06:58 in ♏ Scorpio.

Distance to Moon 366 981 km

The Moon is 366 981 km (228 031 mi) away from Earth and getting further over the next 11 days until the point apogee when Earth-Moon distance is going to be 406 013 km (252 285 mi).

Moon after ascending node

2 days after ascending node on 24 September 2078 at 13:18 in ♉ Taurus the Moon is positioned north of the ecliptic over the following 10 days until the lunar crosses the ecliptic again from North to South in descending node on 8 October 2078 at 06:08 in ♏ Scorpio.

Moon before northern standstill

11 days since the last southern standstill on 15 September 2078 at 16:23 in ♑ Capricorn when the Moon has reached South declination of ∠-27.437° the lunar orbit is extending northward over the next day to face maximum declination of ∠27.518° at the point of next northern standstill on 28 September 2078 at 11:14 in ♋ Cancer.

Draconic month

2 days since the beginning of this draconic month in ♉ Taurus the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 8 days

In 8 days on 5 October 2078 at 23:06 in ♎ Libra 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.
