Last Quarter in Gemini

Last Quarter on . The illuminated surface of the moon is 49% and getting smaller. The lunar cycle is 22 days old.

* The exact date and time of this Last Quarter phase is on 18 September 2098 at 09:33 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 leaving the last ∠3° of ♊ Gemini tropical zodiac sector and will enter ♋ Cancer later.

Hunter Moon after 21 days

Next Full Moon is the Hunter Moon of October 2098 after 21 days on 10 October 2098 at 09:20.

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 ∠1934"

Lunar disc appears visually 1.2% wider than solar disc. Moon and Sun apparent angular diameters are ∠1934" and ∠1910".

Lunation 1220 / 2173

The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 1220 of Meeus index or 2173 from Brown series.

Synodic month length 29.35 days

The length of this lunation is 29 days, 8 hours and 24 minutes and it is 2 hours and 8 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 4 hours and 20 minutes shorter than the mean synodic month length. It is 1 hour and 49 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠10.1°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠10.1° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠26.9°.

Moon before perigee

10 days since point of apogee on 7 September 2098 at 19:51 in ♒ Aquarius the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 4 days until the Moon reaches the point of next perigee on 23 September 2098 at 09:26 in ♍ Virgo.

Distance to Moon 370 695 km

The Moon is 370 695 km (230 339 mi) away from Earth and getting closer over the next 4 days until the point perigee when Earth-Moon distance is going to be 361 024 km (224 330 mi).

Moon after ascending node

5 days after ascending node on 12 September 2098 at 21:33 in ♈ Aries the Moon is positioned north of the ecliptic over the following 7 days until the lunar crosses the ecliptic again from North to South in descending node on 25 September 2098 at 20:31 in ♎ Libra.

Moon at northern standstill

At 20:59 the Moon is meeting its standstill point to reach North declination of ∠28.525°. Over the upcoming 13 days the lunar orbit is going to tilt southward to face maximum declination of ∠-28.555° at the point of next southern standstill in ♐ Sagittarius on 1 October 2098 at 16:08.

Draconic month

5 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 6 days

In 6 days on 25 September 2098 at 00:17 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.
