Waning Gibbous in Gemini

Waning Gibbous on . Illuminated surface of the Moon is 97% and getting smaller. Lunar cycle is 16 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 ∠18° of ♊ Gemini tropical zodiac sector.

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 17 November 2013 at 15:16.

Beaver Moon before 1 day

Next Full Moon is the Cold Moon of December 2013 after 27 days on 17 December 2013 at 09:28.

Moderate tide

There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.

Apparent angular diameter ∠1781"

Lunar disc appears visually 8.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1781" and ∠1942".

Lunation 171 / 1124

The Moon is 16 days old and navigating from the middle to the last part of the current synodic month. This is lunation 171 of Meeus index or 1124 from Brown series.

Synodic month length 29.48 days

The length of this lunation is 29 days, 11 hours and 32 minutes and it is 40 minutes longer than the upcoming lunation's length. 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 1 hour and 12 minutes shorter than the mean synodic month length. It is 4 hours and 57 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠315°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠315° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠336.4°.

Moon before apogee

13 days since point of perigee on 6 November 2013 at 09:28 in ♐ Sagittarius the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 2 days until the Moon reaches the point of next apogee on 22 November 2013 at 09:50 in ♋ Cancer.

Distance to Moon 402 409 km

The Moon is 402 409 km (250 045 mi) away from Earth and getting further over the next 2 days until the point apogee when Earth-Moon distance is going to be 405 446 km (251 932 mi).

Moon after descending node

3 days after descending node on 16 November 2013 at 05:30 in ♉ Taurus the Moon is positioned south of the ecliptic over the following 11 days until the lunar crosses the ecliptic again from South to North in ascending node on 30 November 2013 at 16:59 in ♏ Scorpio.

Moon at northern standstill

At 17:18 the Moon is meeting its standstill point to reach North declination of ∠19.534°. Over the upcoming 14 days the lunar orbit is going to tilt southward to face maximum declination of ∠-19.552° at the point of next southern standstill in ♐ Sagittarius on 3 December 2013 at 16:38.

Draconic month

16 days since the beginning of this draconic month in ♏ Scorpio the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 13 days

In 13 days on 3 December 2013 at 00:22 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.
