First Quarter in Aries

First Quarter on . The illuminated surface of the moon is 52% and growing larger. The lunar cycle is 7 days young.

* The exact date and time of this First Quarter phase is on 31 December 2079 at 08:29 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 ∠12° of ♈ Aries tropical zodiac sector.

Wolf Moon after 6 days

Next Full Moon is the Wolf Moon of January 2080 after 6 days on 7 January 2080 at 01:45.

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 ∠1877"

Lunar disc appears visually 3.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1877" and ∠1951".

Lunation 989 / 1942

The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 989 of Meeus index or 1942 from Brown series.

Synodic month length 29.81 days

The length of this lunation is 29 days, 19 hours and 24 minutes and it is 1 hour and 8 minutes longer than the upcoming lunation's length. This is the year's longest synodic month of 2079. 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 6 hours and 40 minutes longer than the mean synodic month length. It is 23 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠174.6°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠174.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠199.5°.

Moon before perigee

7 days since point of apogee on 23 December 2079 at 21:45 in ♑ Capricorn the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 6 days until the Moon reaches the point of next perigee on 6 January 2080 at 19:49 in ♋ Cancer.

Distance to Moon 381 948 km

The Moon is 381 948 km (237 331 mi) away from Earth and getting closer over the next 6 days until the point perigee when Earth-Moon distance is going to be 356 505 km (221 522 mi).

Moon in ascending node

Moon is in ascending node in ♈ Aries at 23:44 crossing the ecliptic from South to North. Lunar position remains north of if for the upcoming 12 days until Moon's next descending node later on 13 January 2080 at 09:00 in ♎ Libra.

Moon before northern standstill

8 days since the last southern standstill on 23 December 2079 at 10:12 in ♑ Capricorn when the Moon has reached South declination of ∠-28.189° the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠28.224° at the point of next northern standstill on 6 January 2080 at 04:42 in ♋ Cancer.

New draconic month

At 23:44 in the point ot ascending node the Moon is completing the last draconic month and is entering a new one while the lunar orbit is crossing the ecliptic from South to North.

Syzygy in 6 days

In 6 days on 7 January 2080 at 01:45 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.
