Waning Gibbous in Gemini

Waning Gibbous on . Illuminated surface of the Moon is 94% and getting smaller. Lunar cycle is 17 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 ∠20° of ♊ Gemini tropical zodiac sector.

2 days after Full Moon

Previous main lunar phase is the Full Moon before 2 days on 10 November 2011 at 20:16.

Beaver Moon before 2 days

Next Full Moon is the Cold Moon of December 2011 after 27 days on 10 December 2011 at 14:36.

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 ∠1809"

Lunar disc appears visually 6.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1809" and ∠1939".

Lunation 146 / 1099

The Moon is 17 days old and navigating from the middle to the last part of the current synodic month. This is lunation 146 of Meeus index or 1099 from Brown series.

Synodic month length 29.43 days

The length of this lunation is 29 days, 10 hours and 14 minutes and it is 1 hour 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 shorter than mean

The length of the current synodic month is 2 hours and 30 minutes shorter than the mean synodic month length. It is 3 hours and 39 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠5.3°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠5.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠21.6°.

Moon after apogee

4 days since point of apogee on 8 November 2011 at 13:20 in ♈ Aries the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 10 days until the Moon reaches the point of next perigee on 23 November 2011 at 23:24 in ♏ Scorpio.

Distance to Moon 396 188 km

The Moon is 396 188 km (246 180 mi) away from Earth and getting closer over the next 10 days until the point perigee when Earth-Moon distance is going to be 359 692 km (223 502 mi).

Moon in descending node

Moon is in descending node in ♊ Gemini at 00:35 crossing the ecliptic from North to South. Lunar position remains south of if for the upcoming 12 days until Moon's next ascending node later on 26 November 2011 at 01:02 in ♐ Sagittarius.

Moon at northern standstill

At 07:23 the Moon is meeting its standstill point to reach North declination of ∠22.558°. Over the upcoming 12 days the lunar orbit is going to tilt southward to face maximum declination of ∠-22.552° at the point of next southern standstill in ♐ Sagittarius on 26 November 2011 at 06:47.

Draconic month

14 days since the beginning of this draconic month in ♐ Sagittarius the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 11 days

In 11 days on 25 November 2011 at 06:10 in ♐ Sagittarius 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.
