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 11 January 2068 at 17:47 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 ∠18° of ♈ Aries tropical zodiac sector.

Wolf Moon after 7 days

Next Full Moon is the Wolf Moon of January 2068 after 7 days on 19 January 2068 at 09:45.

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 ∠1942"

Lunar disc appears visually 0.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1942" and ∠1951".

Lunation 841 / 1794

The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 841 of Meeus index or 1794 from Brown series.

Synodic month length 29.46 days

The length of this lunation is 29 days, 11 hours and 6 minutes and it is 1 hour and 13 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 shorter than mean

The length of the current synodic month is 1 hour and 38 minutes shorter than the mean synodic month length. It is 4 hours and 31 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠331.1°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠331.1° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠348.6°.

Moon after perigee

4 days since point of perigee on 6 January 2068 at 20:29 in ♒ Aquarius the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 11 days until the Moon reaches the point of next apogee on 22 January 2068 at 15:47 in ♍ Virgo.

Distance to Moon 369 171 km

The Moon is 369 171 km (229 392 mi) away from Earth and getting further over the next 11 days until the point apogee when Earth-Moon distance is going to be 406 042 km (252 303 mi).

Moon before descending node

8 days after ascending node on 2 January 2068 at 18:49 in ♐ Sagittarius the Moon is positioned north of the ecliptic over the following 3 days until the lunar crosses the ecliptic again from North to South in descending node on 15 January 2068 at 11:57 in ♊ Gemini.

Moon before northern standstill

8 days since the last southern standstill on 3 January 2068 at 06:48 in ♐ Sagittarius when the Moon has reached South declination of ∠-22.264° the lunar orbit is extending northward over the next 4 days to face maximum declination of ∠22.237° at the point of next northern standstill on 16 January 2068 at 02:15 in ♊ Gemini.

Draconic month

8 days since the beginning of this draconic month in ♐ Sagittarius the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 7 days

In 7 days on 19 January 2068 at 09:45 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.
