First Quarter in Aries

First Quarter on . The illuminated surface of the moon is 49% and growing larger. The lunar cycle is 7 days young.

* The exact date and time of this First Quarter phase is on 31 December 2068 at 13:23 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 ∠10° of ♈ Aries tropical zodiac sector.

Wolf Moon after 7 days

Next Full Moon is the Wolf Moon of January 2069 after 7 days on 7 January 2069 at 13:43.

Moderate tide

There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.

Apparent angular diameter ∠1973"

Lunar disc appears visually 1.1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1973" and ∠1951".

Lunation 853 / 1806

The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 853 of Meeus index or 1806 from Brown series.

Synodic month length 29.58 days

The length of this lunation is 29 days, 13 hours and 52 minutes and it is 2 hours and 11 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 longer than mean

The length of the current synodic month is 1 hour and 8 minutes longer than the mean synodic month length. It is 5 hours and 55 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠279.4°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠279.4° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠310.8°.

Moon after apogee

13 days since point of apogee on 17 December 2068 at 15:04 in ♎ Libra the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 14 days until the Moon reaches the point of next perigee on 14 January 2069 at 12:33 in ♎ Libra.

Distance to Moon 363 301 km

The Moon is 363 301 km (225 745 mi) away from Earth and getting closer over the next 14 days until the point perigee when Earth-Moon distance is going to be 404 393 km (251 278 mi).

Moon before descending node

10 days after ascending node on 21 December 2068 at 08:54 in ♏ Scorpio the Moon is positioned north of the ecliptic over the following 2 days until the lunar crosses the ecliptic again from North to South in descending node on 3 January 2069 at 11:40 in ♉ Taurus.

Moon before northern standstill

8 days since the last southern standstill on 23 December 2068 at 11:18 in ♐ Sagittarius when the Moon has reached South declination of ∠-20.663° the lunar orbit is extending northward over the next 4 days to face maximum declination of ∠20.637° at the point of next northern standstill on 5 January 2069 at 11:24 in ♊ Gemini.

Draconic month

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

Syzygy in 7 days

In 7 days on 7 January 2069 at 13:43 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.
