First Quarter in Aries

First Quarter on . The illuminated surface of the moon is 58% and growing larger. The lunar cycle is 8 days young.

* The exact date and time of this First Quarter phase is on 1 January 2088 at 17:54 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 ∠22° of ♈ Aries tropical zodiac sector.

Wolf Moon after 5 days

Next Full Moon is the Wolf Moon of January 2088 after 5 days on 8 January 2088 at 09:37.

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 ∠1947"

Lunar disc appears visually 0.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1947" and ∠1951".

Lunation 1088 / 2041

The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 1088 of Meeus index or 2041 from Brown series.

Synodic month length 29.75 days

The length of this lunation is 29 days, 17 hours and 56 minutes and it is 2 hours and 25 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 5 hours and 12 minutes longer than the mean synodic month length. It is 1 hour and 51 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠208.8°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠208.8° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠241.2°.

Moon before perigee

11 days since point of apogee on 22 December 2087 at 02:07 in ♏ Scorpio 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 6 January 2088 at 19:17 in ♊ Gemini.

Distance to Moon 368 229 km

The Moon is 368 229 km (228 807 mi) away from Earth and getting closer over the next 4 days until the point perigee when Earth-Moon distance is going to be 360 758 km (224 165 mi).

Moon before descending node

12 days after ascending node on 21 December 2087 at 00:25 in ♏ Scorpio the Moon is positioned north of the ecliptic over the following day until the lunar crosses the ecliptic again from North to South in descending node on 4 January 2088 at 02:18 in ♉ Taurus.

Moon before northern standstill

9 days since the last southern standstill on 23 December 2087 at 22:55 in ♐ Sagittarius when the Moon has reached South declination of ∠-20.078° the lunar orbit is extending northward over the next 4 days to face maximum declination of ∠20.031° at the point of next northern standstill on 6 January 2088 at 13:10 in ♊ Gemini.

Draconic month

12 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 5 days

In 5 days on 8 January 2088 at 09:37 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.
