Last Quarter in Cancer

Last Quarter on . Illuminated surface of the Moon is 57% and getting smaller. Lunar cycle is 21 days old.

* The exact date and time of this Last Quarter phase is on 10 October 2001 at 04:20 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 ∠8° of ♋ Cancer tropical zodiac sector.

Beaver Moon after 22 days

Next Full Moon is the Beaver Moon of November 2001 after 22 days on 1 November 2001 at 05:41.

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 ∠1926"

Lunar disc appears visually 0.2% wider than solar disc. Moon and Sun apparent angular diameters are ∠1926" and ∠1921".

Lunation 21 / 974

The Moon is 21 days old and navigating through the last part of the current synodic month. This is lunation 21 of Meeus index or 974 from Brown series.

Synodic month length 29.37 days

The length of this lunation is 29 days, 8 hours and 56 minutes and it is 2 hours and 21 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 shorter than mean

The length of the current synodic month is 3 hours and 48 minutes shorter than the mean synodic month length. It is 2 hours and 21 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠13.2°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠13.2° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠30.5°.

Moon before perigee

10 days since point of apogee on 29 September 2001 at 05:33 in ♒ Aquarius the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 5 days until the Moon reaches the point of next perigee on 14 October 2001 at 23:02 in ♍ Virgo.

Distance to Moon 372 214 km

The Moon is 372 214 km (231 283 mi) away from Earth and getting closer over the next 5 days until the point perigee when Earth-Moon distance is going to be 361 864 km (224 852 mi).

Moon after ascending node

1 day after ascending node on 8 October 2001 at 22:32 in ♊ Gemini the Moon is positioned north of the ecliptic over the following 12 days until the lunar crosses the ecliptic again from North to South in descending node on 21 October 2001 at 13:22 in ♐ Sagittarius.

Moon at northern standstill

At 18:46 the Moon is meeting its standstill point to reach North declination of ∠23.937°. Over the upcoming 13 days the lunar orbit is going to tilt southward to face maximum declination of ∠-24.041° at the point of next southern standstill in ♑ Capricorn on 22 October 2001 at 13:05.

Draconic month

1 day since the beginning of this draconic month in ♊ Gemini the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 7 days

In 7 days on 16 October 2001 at 19:23 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.
