Waning Gibbous in Gemini

Waning Gibbous on . The illuminated surface of the moon is 66% and getting smaller. The lunar cycle is 20 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 leaving the last ∠2° of ♊ Gemini tropical zodiac sector and will enter ♋ Cancer later.

6 days after Full Moon

Previous main lunar phase is the Full Moon before 6 days on 3 October 2047 at 23:42.

Hunter Moon before 6 days

Next Full Moon is the Beaver Moon of November 2047 after 23 days on 2 November 2047 at 16:58.

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 ∠1793"

Lunar disc appears visually 7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1793" and ∠1922".

Lunation 590 / 1543

The Moon is 20 days old and navigating from the middle to the last part of the current synodic month. This is lunation 590 of Meeus index or 1543 from Brown series.

Synodic month length 29.37 days

The length of this lunation is 29 days, 8 hours and 57 minutes and it is 34 minutes shorter than the upcoming lunation's length. This is the year's shortest synodic month of 2047. 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 3 hours and 48 minutes shorter than the mean synodic month length. It is 2 hours and 22 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠329.2°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠329.2° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠346.8°.

Moon after apogee

3 days since point of apogee on 7 October 2047 at 08:53 in ♉ Taurus the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 9 days until the Moon reaches the point of next perigee on 19 October 2047 at 21:58 in ♎ Libra.

Distance to Moon 399 842 km

The Moon is 399 842 km (248 450 mi) away from Earth and getting closer over the next 9 days until the point perigee when Earth-Moon distance is going to be 357 956 km (222 424 mi).

Moon before descending node

13 days after ascending node on 27 September 2047 at 01:32 in ♑ Capricorn 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 11 October 2047 at 12:21 in ♋ Cancer.

Moon after northern standstill

1 day since the last northern standstill on 9 October 2047 at 18:12 in ♊ Gemini when the Moon has reached North declination of ∠24.802° the lunar orbit is extending southward over the next 12 days to face maximum declination of ∠-24.711° at the point of next southern standstill on 22 October 2047 at 17:18 in ♐ Sagittarius.

Draconic month

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

Syzygy in 8 days

In 8 days on 19 October 2047 at 03:28 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.
