Waning Gibbous in Cancer

Waning Gibbous on . Illuminated surface of the Moon is 82% 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 is entering ♋ Cancer

Moon is passing first ∠2° of ♋ Cancer tropical zodiac sector.

4 days after Full Moon

Previous main lunar phase is the Full Moon before 4 days on 29 October 2012 at 19:50.

Hunter Moon before 4 days

Next Full Moon is the Beaver Moon of November 2012 after 25 days on 28 November 2012 at 14:46.

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 ∠1778"

Lunar disc appears visually 8.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1778" and ∠1935".

Lunation 158 / 1111

The Moon is 19 days old and navigating from the middle to the last part of the current synodic month. This is lunation 158 of Meeus index or 1111 from Brown series.

Synodic month length 29.42 days

The length of this lunation is 29 days, 10 hours and 5 minutes and it is 29 minutes shorter 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 2 hours and 39 minutes shorter than the mean synodic month length. It is 3 hours and 30 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠334.3°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠334.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠351.3°.

Moon after apogee

1 day since point of apogee on 1 November 2012 at 15:30 in ♊ Gemini 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 14 November 2012 at 10:21 in ♏ Scorpio.

Distance to Moon 403 142 km

The Moon is 403 142 km (250 501 mi) away from Earth and getting closer over the next 10 days until the point perigee when Earth-Moon distance is going to be 357 361 km (222 054 mi).

Moon after descending node

3 days after descending node on 31 October 2012 at 10:36 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 14 November 2012 at 04:37 in ♏ Scorpio.

Moon after northern standstill

1 day since the last northern standstill on 2 November 2012 at 08:15 in ♊ Gemini when the Moon has reached North declination of ∠20.920° the lunar orbit is extending southward over the next 12 days to face maximum declination of ∠-20.914° at the point of next southern standstill on 15 November 2012 at 16:10 in ♐ Sagittarius.

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 10 days

In 10 days on 13 November 2012 at 22:08 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.
