Last Quarter in Cancer

Last Quarter on . Illuminated surface of the Moon is 50% and getting smaller. Lunar cycle is 22 days old.

* The exact date and time of this Last Quarter phase is on 8 October 2031 at 10:50 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 ∠16° of ♋ Cancer tropical zodiac sector.

Hunter Moon after 21 days

Next Full Moon is the Hunter Moon of October 2031 after 21 days on 30 October 2031 at 07:33.

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 ∠1769"

Lunar disc appears visually 8.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1769" and ∠1921".

Lunation 392 / 1345

The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 392 of Meeus index or 1345 from Brown series.

Synodic month length 29.57 days

The length of this lunation is 29 days, 13 hours and 34 minutes and it is 45 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 longer than mean

The length of the current synodic month is 50 minutes longer than the mean synodic month length. It is 6 hours and 13 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠245.2°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠245.2° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠281.8°.

Moon before apogee

11 days since point of perigee on 27 September 2031 at 07:09 in ♒ Aquarius 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 9 October 2031 at 06:23 in ♋ Cancer.

Distance to Moon 405 151 km

The Moon is 405 151 km (251 749 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 404 365 km (251 261 mi).

Moon after descending node

4 days after descending node on 3 October 2031 at 22:04 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 18 October 2031 at 06:54 in ♏ Scorpio.

Moon after northern standstill

2 days since the last northern standstill on 6 October 2031 at 07:31 in ♊ Gemini when the Moon has reached North declination of ∠20.418° the lunar orbit is extending southward over the next 11 days to face maximum declination of ∠-20.359° at the point of next southern standstill on 20 October 2031 at 11:06 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 16 October 2031 at 08:21 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.
