Waning Gibbous in Gemini

Waning Gibbous on . Illuminated surface of the Moon is 80% and getting smaller. Lunar cycle is 19 days old.

Moonrise and moonset

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.

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon in ♊ Gemini

Moon is passing about ∠23° of ♊ Gemini tropical zodiac sector.

4 days after Full Moon

Previous main lunar phase is the Full Moon before 4 days on 17 October 2081 at 20:50.

Hunter Moon before 4 days

Next Full Moon is the Beaver Moon of November 2081 after 25 days on 16 November 2081 at 13:19.

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 ∠1872"

Lunar disc appears visually 3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1872" and ∠1929".

Lunation 1011 / 1964

The Moon is 19 days old and navigating from the middle to the last part of the current synodic month. This is lunation 1011 of Meeus index or 1964 from Brown series.

Synodic month length 29.4 days

The length of this lunation is 29 days, 9 hours and 41 minutes and it is 1 hour and 51 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 shorter than mean

The length of the current synodic month is 3 hours and 3 minutes shorter than the mean synodic month length. It is 3 hours and 6 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠12.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠12.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠29.7°.

Moon before perigee

7 days since point of apogee on 14 October 2081 at 14:03 in ♓ Pisces 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 30 October 2081 at 07:55 in ♎ Libra.

Distance to Moon 382 967 km

The Moon is 382 967 km (237 965 mi) away from Earth and getting closer over the next 7 days until the point perigee when Earth-Moon distance is going to be 361 740 km (224 775 mi).

Moon before descending node

8 days after ascending node on 14 October 2081 at 11:52 in ♓ Pisces the Moon is positioned north of the ecliptic over the following 5 days until the lunar crosses the ecliptic again from North to South in descending node on 28 October 2081 at 09:25 in ♍ Virgo.

Moon at northern standstill

At 20:04 the Moon is meeting its standstill point to reach North declination of ∠28.369°. Over the upcoming 13 days the lunar orbit is going to tilt southward to face maximum declination of ∠-28.291° at the point of next southern standstill in ♐ Sagittarius on 4 November 2081 at 12:34.

Draconic month

8 days since the beginning of this draconic month in ♓ Pisces the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 9 days

In 9 days on 1 November 2081 at 03:04 in ♏ Scorpio 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.
