First Quarter in Aries

First Quarter on . The illuminated surface of the moon is 47% and growing larger. The lunar cycle is 7 days young.

* The exact date and time of this First Quarter phase is on 27 December 2063 at 20:57 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 is entering ♈ Aries

Moon is passing first ∠2° of ♈ Aries tropical zodiac sector.

Wolf Moon after 7 days

Next Full Moon is the Wolf Moon of January 2064 after 7 days on 4 January 2064 at 09:31.

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 ∠1771"

Lunar disc appears visually 9.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1771" and ∠1951".

Lunation 791 / 1744

The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 791 of Meeus index or 1744 from Brown series.

Synodic month length 29.69 days

The length of this lunation is 29 days, 16 hours and 33 minutes and it is 1 hour and 53 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 longer than mean

The length of the current synodic month is 3 hours and 49 minutes longer than the mean synodic month length. It is 3 hours and 14 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠88.4°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠88.4° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠125.9°.

Moon after apogee

1 day since point of apogee on 26 December 2063 at 09:48 in ♓ Pisces the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 10 days until the Moon reaches the point of next perigee on 7 January 2064 at 03:30 in ♌ Leo.

Distance to Moon 404 732 km

The Moon is 404 732 km (251 489 mi) away from Earth and getting closer over the next 10 days until the point perigee when Earth-Moon distance is going to be 365 135 km (226 884 mi).

Moon after ascending node

3 days after ascending node on 24 December 2063 at 11:46 in ♒ Aquarius the Moon is positioned north of the ecliptic over the following 10 days until the lunar crosses the ecliptic again from North to South in descending node on 7 January 2064 at 06:27 in ♌ Leo.

Moon before northern standstill

7 days since the last southern standstill on 19 December 2063 at 14:21 in ♐ Sagittarius when the Moon has reached South declination of ∠-27.752° the lunar orbit is extending northward over the next 6 days to face maximum declination of ∠27.781° at the point of next northern standstill on 3 January 2064 at 00:55 in ♋ Cancer.

Draconic month

3 days since the beginning of this draconic month in ♒ Aquarius the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 7 days

In 7 days on 4 January 2064 at 09:31 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.
