Last Quarter in Gemini

Last Quarter on . The illuminated surface of the moon is 46% and getting smaller. The lunar cycle is 22 days old.

* The exact date and time of this Last Quarter phase is on 21 August 2087 at 03:34 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 ♊ Gemini

Moon is passing first ∠3° of ♊ Gemini tropical zodiac sector.

Harvest Moon after 22 days

Next Full Moon is the Harvest Moon of September 2087 after 22 days on 12 September 2087 at 16:43.

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 ∠1970"

Lunar disc appears visually 3.8% wider than solar disc. Moon and Sun apparent angular diameters are ∠1970" and ∠1897".

Lunation 1083 / 2036

The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 1083 of Meeus index or 2036 from Brown series.

Synodic month length 29.45 days

The length of this lunation is 29 days, 10 hours and 48 minutes and it is 2 hours and 51 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 1 hour and 56 minutes shorter than the mean synodic month length. It is 4 hours and 13 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠62.7°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠62.7° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠95.4°.

Moon after perigee

2 days since point of perigee on 19 August 2087 at 10:24 in ♉ Taurus 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 3 September 2087 at 11:42 in ♏ Scorpio.

Distance to Moon 363 881 km

The Moon is 363 881 km (226 105 mi) away from Earth and getting further over the next 12 days until the point apogee when Earth-Moon distance is going to be 404 474 km (251 328 mi).

Moon after descending node

1 day after descending node on 20 August 2087 at 13:00 in ♉ Taurus the Moon is positioned south of the ecliptic over the following 12 days until the lunar crosses the ecliptic again from South to North in ascending node on 3 September 2087 at 03:54 in ♏ Scorpio.

Moon before northern standstill

12 days since the last southern standstill on 9 August 2087 at 10:48 in ♐ Sagittarius when the Moon has reached South declination of ∠-20.587° the lunar orbit is extending northward over the next day to face maximum declination of ∠20.473° at the point of next northern standstill on 22 August 2087 at 16:14 in ♊ Gemini.

Draconic month

14 days since the beginning of this draconic month in ♏ Scorpio the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 6 days

In 6 days on 28 August 2087 at 05:08 in ♍ Virgo 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.
