First Quarter in Aries

First Quarter on . The illuminated surface of the moon is 60% and growing larger. The lunar cycle is 8 days young.

* The exact date and time of this First Quarter phase is on 14 December 2075 at 14:37 UTC.

Moonrise and moonset

The moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.

Moon phase and lunation details

Moon in ♈ Aries

Moon is passing about ∠5° of ♈ Aries tropical zodiac sector.

Cold Moon after 6 days

Next Full Moon is the Cold Moon of December 2075 after 6 days on 22 December 2075 at 08:48.

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 ∠1904"

Lunar disc appears visually 2.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1904" and ∠1950".

Lunation 939 / 1892

The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 939 of Meeus index or 1892 from Brown series.

Synodic month length 29.47 days

The length of this lunation is 29 days, 11 hours and 11 minutes and it is 24 minutes longer than the upcoming lunation's length. This is the year's shortest synodic month of 2075. 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 1 hour and 33 minutes shorter than the mean synodic month length. It is 4 hours and 36 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠337.3°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠337.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠354°.

Moon after perigee

6 days since point of perigee on 9 December 2075 at 07:28 in ♑ Capricorn the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 9 days until the Moon reaches the point of next apogee on 24 December 2075 at 19:52 in ♋ Cancer.

Distance to Moon 376 484 km

The Moon is 376 484 km (233 936 mi) away from Earth and getting further over the next 9 days until the point apogee when Earth-Moon distance is going to be 406 155 km (252 373 mi).

Moon after descending node

6 days after descending node on 9 December 2075 at 06:27 in ♑ Capricorn the Moon is positioned south of the ecliptic over the following 7 days until the lunar crosses the ecliptic again from South to North in ascending node on 22 December 2075 at 18:35 in ♊ Gemini.

Moon after southern standstill

5 days since the last southern standstill on 9 December 2075 at 16:59 in ♑ Capricorn when the Moon has reached South declination of ∠-23.506° the lunar orbit is extending northward over the next 7 days to face maximum declination of ∠23.513° at the point of next northern standstill on 23 December 2075 at 08:11 in ♋ Cancer.

Draconic month

19 days since the beginning of this draconic month in ♋ Cancer the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 6 days

In 6 days on 22 December 2075 at 08:48 in ♋ Cancer the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
