Last Quarter in Aries

Last Quarter on . The illuminated surface of the moon is 44% and getting smaller. The lunar cycle is 22 days old.

* The exact date and time of this Last Quarter phase is on 15 June 2009 at 22:15 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 is entering ♈ Aries

Moon is passing first ∠2° of ♈ Aries tropical zodiac sector.

Buck Moon after 20 days

Next Full Moon is the Buck Moon of July 2009 after 20 days on 7 July 2009 at 09:21.

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 ∠1842"

Lunar disc appears visually 2.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1842" and ∠1889".

Lunation 116 / 1069

The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 116 of Meeus index or 1069 from Brown series.

Synodic month length 29.31 days

The length of this lunation is 29 days, 7 hours and 24 minutes and it is 24 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 shorter than mean

The length of the current synodic month is 5 hours and 20 minutes shorter than the mean synodic month length. It is 49 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠332.7°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠332.7° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠349.4°.

Moon after apogee

5 days since point of apogee on 10 June 2009 at 16:04 in ♑ Capricorn the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 6 days until the Moon reaches the point of next perigee on 23 June 2009 at 10:39 in ♋ Cancer.

Distance to Moon 389 110 km

The Moon is 389 110 km (241 782 mi) away from Earth and getting closer over the next 6 days until the point perigee when Earth-Moon distance is going to be 358 018 km (222 462 mi).

Moon after ascending node

5 days after ascending node on 11 June 2009 at 10:15 in ♒ Aquarius the Moon is positioned north of the ecliptic over the following 8 days until the lunar crosses the ecliptic again from North to South in descending node on 24 June 2009 at 17:24 in ♋ Cancer.

Moon before northern standstill

8 days since the last southern standstill on 8 June 2009 at 02:03 in ♐ Sagittarius when the Moon has reached South declination of ∠-26.429° the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠26.446° at the point of next northern standstill on 22 June 2009 at 02:48 in ♊ Gemini.

Draconic month

5 days since the beginning of this draconic month in ♒ Aquarius the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 6 days

In 6 days on 22 June 2009 at 19:35 in ♊ Gemini 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.
