Last Quarter in Cancer

Last Quarter on . Illuminated surface of the Moon is 48% and getting smaller. Lunar cycle is 22 days old.

* The exact date and time of this Last Quarter phase is on 8 October 2012 at 07:33 UTC.

Moonrise and moonset

Moon rises at midnight and sets at noon. It is visible to the south in the morning.

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon in ♋ Cancer

Moon is passing about ∠18° of ♋ Cancer tropical zodiac sector.

Hunter Moon after 21 days

Next Full Moon is the Hunter Moon of October 2012 after 21 days on 29 October 2012 at 19:50.

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 ∠1798"

Lunar disc appears visually 6.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1798" and ∠1921".

Lunation 157 / 1110

The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 157 of Meeus index or 1110 from Brown series.

Synodic month length 29.41 days

The length of this lunation is 29 days, 9 hours and 52 minutes and it is 13 minutes shorter than the upcoming lunation's length. This is the year's shortest synodic month of 2012. 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 52 minutes shorter than the mean synodic month length. It is 3 hours and 17 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠312.9°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠312.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠334.3°.

Moon after apogee

3 days since point of apogee on 5 October 2012 at 00:43 in ♊ Gemini the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 8 days until the Moon reaches the point of next perigee on 17 October 2012 at 01:02 in ♏ Scorpio.

Distance to Moon 398 695 km

The Moon is 398 695 km (247 738 mi) away from Earth and getting closer over the next 8 days until the point perigee when Earth-Moon distance is going to be 360 673 km (224 112 mi).

Moon after descending node

4 days after descending node on 4 October 2012 at 05:15 in ♉ Taurus the Moon is positioned south of the ecliptic over the following 9 days until the lunar crosses the ecliptic again from South to North in ascending node on 17 October 2012 at 18:27 in ♏ Scorpio.

Moon after northern standstill

2 days since the last northern standstill on 6 October 2012 at 01:40 in ♊ Gemini when the Moon has reached North declination of ∠21.024° the lunar orbit is extending southward over the next 10 days to face maximum declination of ∠-20.964° at the point of next southern standstill on 19 October 2012 at 06:49 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 7 days

In 7 days on 15 October 2012 at 12:02 in ♎ Libra 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.
