Last Quarter in Gemini

Last Quarter on . Illuminated surface of the Moon is 46% and getting smaller. Lunar cycle is 22 days old.

* The exact date and time of this Last Quarter phase is on 20 August 2003 at 00:48 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 is entering ♊ Gemini

Moon is passing first ∠2° of ♊ Gemini tropical zodiac sector.

Harvest Moon after 21 days

Next Full Moon is the Harvest Moon of September 2003 after 21 days on 10 September 2003 at 16:36.

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 ∠1770"

Lunar disc appears visually 6.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1770" and ∠1896".

Lunation 44 / 997

The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 44 of Meeus index or 997 from Brown series.

Synodic month length 29.44 days

The length of this lunation is 29 days, 10 hours and 34 minutes and it is 51 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 2 hours and 10 minutes shorter than the mean synodic month length. It is 3 hours and 59 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠268.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠268.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠301°.

Moon after apogee

1 day since point of apogee on 19 August 2003 at 14:22 in ♉ Taurus the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 11 days until the Moon reaches the point of next perigee on 31 August 2003 at 18:47 in ♎ Libra.

Distance to Moon 405 053 km

The Moon is 405 053 km (251 688 mi) away from Earth and getting closer over the next 11 days until the point perigee when Earth-Moon distance is going to be 367 929 km (228 620 mi).

Moon after ascending node

1 day after ascending node on 19 August 2003 at 21:08 in ♉ Taurus 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 2 September 2003 at 07:23 in ♏ Scorpio.

Moon before northern standstill

11 days since the last southern standstill on 9 August 2003 at 06:19 in ♑ Capricorn when the Moon has reached South declination of ∠-26.553° the lunar orbit is extending northward over the next 2 days to face maximum declination of ∠26.649° at the point of next northern standstill on 23 August 2003 at 11:41 in ♋ Cancer.

Draconic month

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

Syzygy in 7 days

In 7 days on 27 August 2003 at 17:26 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.
