Last Quarter in Cancer

Last Quarter on . The illuminated surface of the moon is 58% and getting smaller. The lunar cycle is 21 days old.

* The exact date and time of this Last Quarter phase is on 26 October 2100 at 07:19 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 ∠23° of ♋ Cancer tropical zodiac sector.

Beaver Moon after 22 days

Next Full Moon is the Beaver Moon of November 2100 after 22 days on 16 November 2100 at 22:19.

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 ∠1831"

Lunar disc appears visually 5.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1831" and ∠1930".

Lunation 1246 / 2199

The Moon is 21 days old and navigating through the last part of the current synodic month. This is lunation 1246 of Meeus index or 2199 from Brown series.

Synodic month length 29.38 days

The length of this lunation is 29 days, 9 hours and 12 minutes and it is 34 minutes shorter than the upcoming lunation's length. This is the year's shortest synodic month of 2100. 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 3 hours and 32 minutes shorter than the mean synodic month length. It is 2 hours and 37 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠340.4°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠340.4° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠356.4°.

Moon after apogee

5 days since point of apogee on 20 October 2100 at 04:03 in ♉ Taurus the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 7 days until the Moon reaches the point of next perigee on 2 November 2100 at 08:19 in ♏ Scorpio.

Distance to Moon 391 519 km

The Moon is 391 519 km (243 279 mi) away from Earth and getting closer over the next 7 days until the point perigee when Earth-Moon distance is going to be 356 834 km (221 726 mi).

Moon before descending node

11 days after ascending node on 14 October 2100 at 06:36 in ♓ Pisces the Moon is positioned north of the ecliptic over the following 3 days until the lunar crosses the ecliptic again from North to South in descending node on 28 October 2100 at 20:12 in ♌ Leo.

Moon after northern standstill

2 days since the last northern standstill on 23 October 2100 at 08:12 in ♊ Gemini when the Moon has reached North declination of ∠28.129° the lunar orbit is extending southward over the next 10 days to face maximum declination of ∠-28.051° at the point of next southern standstill on 5 November 2100 at 05:15 in ♐ Sagittarius.

Draconic month

11 days since the beginning of this draconic month in ♓ Pisces the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 7 days

In 7 days on 2 November 2100 at 03:14 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.
