Last Quarter in Cancer

Last Quarter on . Illuminated surface of the Moon is 55% and getting smaller. Lunar cycle is 21 days old.

* The exact date and time of this Last Quarter phase is on 25 October 2005 at 01:17 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 ∠25° of ♋ Cancer tropical zodiac sector.

Beaver Moon after 22 days

Next Full Moon is the Beaver Moon of November 2005 after 22 days on 16 November 2005 at 00:58.

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 ∠1777"

Lunar disc appears visually 8.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1777" and ∠1930".

Lunation 71 / 1024

The Moon is 21 days old and navigating through the last part of the current synodic month. This is lunation 71 of Meeus index or 1024 from Brown series.

Synodic month length 29.62 days

The length of this lunation is 29 days, 14 hours and 57 minutes and it is 1 hour and 21 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 2 hours and 13 minutes longer than the mean synodic month length. It is 4 hours and 50 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠236.1°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠236.1° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠273.1°.

Moon before apogee

9 days since point of perigee on 14 October 2005 at 13:50 in ♓ Pisces 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 26 October 2005 at 09:34 in ♌ Leo.

Distance to Moon 403 404 km

The Moon is 403 404 km (250 664 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 404 493 km (251 340 mi).

Moon before descending node

7 days after ascending node on 16 October 2005 at 18:25 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 31 October 2005 at 00:32 in ♎ Libra.

Moon after northern standstill

1 day since the last northern standstill on 22 October 2005 at 15:02 in ♊ Gemini when the Moon has reached North declination of ∠28.583° the lunar orbit is extending southward over the next 12 days to face maximum declination of ∠-28.529° at the point of next southern standstill on 5 November 2005 at 22:03 in ♐ Sagittarius.

Draconic month

7 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 8 days

In 8 days on 2 November 2005 at 01:25 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.
