Last Quarter in Aries

Last Quarter on . Illuminated surface of the Moon is 53% and getting smaller. Lunar cycle is 21 days old.

* The exact date and time of this Last Quarter phase is on 17 July 2006 at 19:13 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 ♈ Aries

Moon is passing about ∠21° of ♈ Aries tropical zodiac sector.

Sturgeon Moon after 22 days

Next Full Moon is the Sturgeon Moon of August 2006 after 22 days on 9 August 2006 at 10:54.

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 ∠1958"

Lunar disc appears visually 3.7% wider than solar disc. Moon and Sun apparent angular diameters are ∠1958" and ∠1888".

Lunation 80 / 1033

The Moon is 21 days old and navigating through the last part of the current synodic month. This is lunation 80 of Meeus index or 1033 from Brown series.

Synodic month length 29.52 days

The length of this lunation is 29 days, 12 hours and 26 minutes and it is 2 hours and 13 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 18 minutes shorter than the mean synodic month length. It is 5 hours and 51 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠97.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠97.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠131.2°.

Moon after perigee

3 days since point of perigee on 13 July 2006 at 17:35 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 12 days until the Moon reaches the point of next apogee on 29 July 2006 at 13:02 in ♍ Virgo.

Distance to Moon 366 052 km

The Moon is 366 052 km (227 454 mi) away from Earth and getting further over the next 12 days until the point apogee when Earth-Moon distance is going to be 405 405 km (251 907 mi).

Moon after ascending node

1 day after ascending node on 15 July 2006 at 20:25 in ♓ Pisces 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 29 July 2006 at 16:58 in ♍ Virgo.

Moon before northern standstill

7 days since the last southern standstill on 9 July 2006 at 18:49 in ♐ Sagittarius when the Moon has reached South declination of ∠-28.477° the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠28.515° at the point of next northern standstill on 22 July 2006 at 14:34 in ♊ Gemini.

Draconic month

1 day 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 25 July 2006 at 04:31 in ♌ Leo 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.
