Waning Gibbous in Cancer

Waning Gibbous on . Illuminated surface of the Moon is 92% 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 is entering ♋ Cancer

Moon is passing first ∠0° of ♋ Cancer tropical zodiac sector.

2 days after Full Moon

Previous main lunar phase is the Full Moon before 2 days on 17 November 2013 at 15:16.

Beaver Moon before 2 days

Next Full Moon is the Cold Moon of December 2013 after 26 days on 17 December 2013 at 09:28.

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 ∠1773"

Lunar disc appears visually 9.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1773" and ∠1942".

Lunation 171 / 1124

The Moon is 17 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

14 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 day until the Moon reaches the point of next apogee on 22 November 2013 at 09:50 in ♋ Cancer.

Distance to Moon 404 343 km

The Moon is 404 343 km (251 247 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 405 446 km (251 932 mi).

Moon after descending node

4 days after descending node on 16 November 2013 at 05:30 in ♉ Taurus the Moon is positioned south of the ecliptic over the following 10 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 after northern standstill

1 day since the last northern standstill on 19 November 2013 at 17:18 in ♊ Gemini when the Moon has reached North declination of ∠19.534° the lunar orbit is extending southward over the next 13 days to face maximum declination of ∠-19.552° at the point of next southern standstill on 3 December 2013 at 16:38 in ♐ Sagittarius.

Draconic month

17 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 12 days

In 12 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.
