Waning Gibbous in Gemini

Waning Gibbous on . Illuminated surface of the Moon is 81% 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 leaving the last ∠4° of ♊ Gemini tropical zodiac sector and will enter ♋ Cancer later.

4 days after Full Moon

Previous main lunar phase is the Full Moon before 4 days on 23 October 2010 at 01:36.

Hunter Moon before 4 days

Next Full Moon is the Beaver Moon of November 2010 after 25 days on 21 November 2010 at 17:27.

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 ∠1892"

Lunar disc appears visually 2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1892" and ∠1931".

Lunation 133 / 1086

The Moon is 19 days old and navigating from the middle to the last part of the current synodic month. This is lunation 133 of Meeus index or 1086 from Brown series.

Synodic month length 29.42 days

The length of this lunation is 29 days, 10 hours and 7 minutes and it is 2 hours and 37 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 2 hours and 37 minutes shorter than the mean synodic month length. It is 3 hours and 32 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠20.4°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠20.4° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠39.7°.

Moon before perigee

8 days since point of apogee on 18 October 2010 at 18:18 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 3 November 2010 at 17:22 in ♎ Libra.

Distance to Moon 378 851 km

The Moon is 378 851 km (235 407 mi) away from Earth and getting closer over the next 7 days until the point perigee when Earth-Moon distance is going to be 364 189 km (226 297 mi).

Moon before descending node

13 days after ascending node on 13 October 2010 at 15:36 in ♐ Sagittarius 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 28 October 2010 at 03:15 in ♋ Cancer.

Moon after northern standstill

1 day since the last northern standstill on 26 October 2010 at 22:36 in ♊ Gemini when the Moon has reached North declination of ∠24.337° the lunar orbit is extending southward over the next 12 days to face maximum declination of ∠-24.281° at the point of next southern standstill on 8 November 2010 at 16:59 in ♐ Sagittarius.

Draconic month

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

Syzygy in 9 days

In 9 days on 6 November 2010 at 04:52 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.
