Last Quarter in Cancer

Last Quarter on . The illuminated surface of the moon is 50% and getting smaller. The lunar cycle is 22 days old.

* The exact date and time of this Last Quarter phase is on 17 October 2079 at 11:22 UTC.

Moonrise and moonset

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

Moon phase and lunation details

Moon in ♋ Cancer

Moon is passing about ∠25° of ♋ Cancer tropical zodiac sector.

Beaver Moon after 22 days

Next Full Moon is the Beaver Moon of November 2079 after 22 days on 9 November 2079 at 04:34.

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 ∠1964"

Lunar disc appears visually 1.9% wider than solar disc. Moon and Sun apparent angular diameters are ∠1964" and ∠1926".

Lunation 986 / 1939

The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 986 of Meeus index or 1939 from Brown series.

Synodic month length 29.59 days

The length of this lunation is 29 days, 14 hours and 14 minutes and it is 2 hours and 56 minutes shorter than the upcoming lunation's length. The lengths of the following synodic months are going to increase with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).

Lunation length longer than mean

The length of the current synodic month is 1 hour and 30 minutes longer than the mean synodic month length. It is 5 hours and 33 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠80.4°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠80.4° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠116.3°.

Moon after perigee

3 days since point of perigee on 14 October 2079 at 02:01 in ♊ Gemini the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 12 days until the Moon reaches the point of next apogee on 29 October 2079 at 23:36 in ♐ Sagittarius.

Distance to Moon 365 022 km

The Moon is 365 022 km (226 814 mi) away from Earth and getting further over the next 12 days until the point apogee when Earth-Moon distance is going to be 405 274 km (251 826 mi).

Moon after ascending node

6 days after ascending node on 11 October 2079 at 01:09 in ♈ Aries the Moon is positioned north of the ecliptic over the following 6 days until the lunar crosses the ecliptic again from North to South in descending node on 24 October 2079 at 00:33 in ♎ Libra.

Moon after northern standstill

1 day since the last northern standstill on 16 October 2079 at 01:29 in ♋ Cancer when the Moon has reached North declination of ∠28.379° the lunar orbit is extending southward over the next 12 days to face maximum declination of ∠-28.363° at the point of next southern standstill on 29 October 2079 at 22:08 in ♐ Sagittarius.

Draconic month

6 days since the beginning of this draconic month in ♈ Aries the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 7 days

In 7 days on 24 October 2079 at 18:19 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.
