Waning Gibbous in Gemini

Waning Gibbous on . The illuminated surface of the moon is 91% and getting smaller. The lunar cycle is 17 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 ∠18° of ♊ Gemini tropical zodiac sector.

2 days after Full Moon

Previous main lunar phase is the Full Moon before 2 days on 2 November 2009 at 19:14.

Beaver Moon before 2 days

Next Full Moon is the Cold Moon of December 2009 after 26 days on 2 December 2009 at 07:30.

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 ∠1942"

Lunar disc appears visually 0.3% wider than solar disc. Moon and Sun apparent angular diameters are ∠1942" and ∠1936".

Lunation 121 / 1074

The Moon is 17 days old and navigating from the middle to the last part of the current synodic month. This is lunation 121 of Meeus index or 1074 from Brown series.

Synodic month length 29.57 days

The length of this lunation is 29 days, 13 hours and 41 minutes and it is 3 hours and 7 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 57 minutes longer than the mean synodic month length. It is 6 hours and 6 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠65.2°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠65.2° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠99.9°.

Moon before perigee

10 days since point of apogee on 25 October 2009 at 23:18 in ♑ Capricorn the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next day until the Moon reaches the point of next perigee on 7 November 2009 at 07:30 in ♋ Cancer.

Distance to Moon 369 144 km

The Moon is 369 144 km (229 375 mi) away from Earth and getting closer over the next day until the point perigee when Earth-Moon distance is going to be 368 900 km (229 224 mi).

Moon before descending node

11 days after ascending node on 25 October 2009 at 08:52 in ♑ Capricorn the Moon is positioned north of the ecliptic over the following 2 days until the lunar crosses the ecliptic again from North to South in descending node on 7 November 2009 at 23:25 in ♋ Cancer.

Moon at northern standstill

At 15:31 the Moon is meeting its standstill point to reach North declination of ∠25.856°. Over the upcoming 13 days the lunar orbit is going to tilt southward to face maximum declination of ∠-25.795° at the point of next southern standstill in ♐ Sagittarius on 18 November 2009 at 19:53.

Draconic month

11 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 11 days

In 11 days on 16 November 2009 at 19:14 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.
