Waning Gibbous in Cancer

Waning Gibbous on . Illuminated surface of the Moon is 79% 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 ♋ Cancer

Moon is passing about ∠24° of ♋ Cancer tropical zodiac sector.

4 days after Full Moon

Previous main lunar phase is the Full Moon before 4 days on 17 November 2013 at 15:16.

Beaver Moon before 4 days

Next Full Moon is the Cold Moon of December 2013 after 24 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 ∠1768"

Lunar disc appears visually 9.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1943".

Lunation 171 / 1124

The Moon is 19 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 at apogee

Moon is at apogee at 09:50 about 16 days since last perigee on 6 November 2013 at 09:28 in ♐ Sagittarius the lunar orbit is going to narrow while the Moon is moving towards the Earth over the upcoming 11 days until point of next perigee on 4 December 2013 at 10:15 in ♑ Capricorn.

Distance to Moon 405 446 km

This apogee Moon is 405 446 km (251 932 mi) away from Earth. It is 38 km further than the mean apogee distance, but it is still 1 263 km closer than the farthest apogee of 21st century.

Moon after descending node

6 days after descending node on 16 November 2013 at 05:30 in ♉ Taurus the Moon is positioned south of the ecliptic over the following 8 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

2 days 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 11 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

19 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 10 days

In 10 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.
