Last Quarter in Gemini

Last Quarter on . The illuminated surface of the moon is 58% and getting smaller. The lunar cycle is 21 days old.

* The exact date and time of this Last Quarter phase is on 17 September 2041 at 05:33 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 in ♊ Gemini

Moon is passing about ∠15° of ♊ Gemini tropical zodiac sector.

Hunter Moon after 23 days

Next Full Moon is the Hunter Moon of October 2041 after 23 days on 9 October 2041 at 18:03.

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 ∠1861"

Lunar disc appears visually 2.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1861" and ∠1909".

Lunation 515 / 1468

The Moon is 21 days old and navigating through the last part of the current synodic month. This is lunation 515 of Meeus index or 1468 from Brown series.

Synodic month length 29.68 days

The length of this lunation is 29 days, 16 hours and 25 minutes and it is 24 minutes shorter 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 longer than mean

The length of the current synodic month is 3 hours and 41 minutes longer than the mean synodic month length. It is 3 hours and 22 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠176.4°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠176.4° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠200.1°.

Moon after perigee

6 days since point of perigee on 10 September 2041 at 02:12 in ♓ Pisces the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 6 days until the Moon reaches the point of next apogee on 23 September 2041 at 04:59 in ♍ Virgo.

Distance to Moon 385 077 km

The Moon is 385 077 km (239 276 mi) away from Earth and getting further over the next 6 days until the point apogee when Earth-Moon distance is going to be 406 361 km (252 501 mi).

Moon after ascending node

2 days after ascending node on 13 September 2041 at 16:25 in ♈ Aries the Moon is positioned north of the ecliptic over the following 11 days until the lunar crosses the ecliptic again from North to South in descending node on 28 September 2041 at 03:42 in ♏ Scorpio.

Moon before northern standstill

10 days since the last southern standstill on 5 September 2041 at 12:54 in ♑ Capricorn when the Moon has reached South declination of ∠-27.620° the lunar orbit is extending northward over the next day to face maximum declination of ∠27.700° at the point of next northern standstill on 18 September 2041 at 03:03 in ♋ Cancer.

Draconic month

2 days since the beginning of this draconic month in ♈ Aries the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 8 days

In 8 days on 25 September 2041 at 08:41 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.
