First Quarter in Aries

First Quarter on . Illuminated surface of the Moon is 47% and growing larger. Lunar cycle is 7 days young.

* The exact date and time of this First Quarter phase is on 19 January 2089 at 19:47 UTC.

Moonrise and moonset

Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon in ♈ Aries

Moon is leaving the last ∠4° of ♈ Aries tropical zodiac sector and will enter ♉ Taurus later.

Wolf Moon after 6 days

Next Full Moon is the Wolf Moon of January 2089 after 6 days on 26 January 2089 at 11:25.

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 ∠1887"

Lunar disc appears visually 3.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1887" and ∠1950".

Lunation 1101 / 2054

The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 1101 of Meeus index or 2054 from Brown series.

Synodic month length 29.79 days

The length of this lunation is 29 days, 18 hours and 58 minutes and it is 1 hour and 50 minutes longer than the upcoming lunation's length. This is the year's longest synodic month of 2089. 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 14 minutes longer than the mean synodic month length. It is 49 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠185.7°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠185.7° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠211.9°.

Moon before perigee

8 days since point of apogee on 11 January 2089 at 04:23 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 25 January 2089 at 19:36 in ♋ Cancer.

Distance to Moon 379 827 km

The Moon is 379 827 km (236 014 mi) away from Earth and getting closer over the next 6 days until the point perigee when Earth-Moon distance is going to be 357 298 km (222 015 mi).

Moon in descending node

Moon is in descending node in ♈ Aries at 04:30 crossing the ecliptic from North to South. Lunar position remains south of if for the upcoming 12 days until Moon's next ascending node later on 31 January 2089 at 14:33 in ♎ Libra.

Moon before northern standstill

10 days since the last southern standstill on 9 January 2089 at 11:54 in ♐ Sagittarius when the Moon has reached South declination of ∠-18.913° the lunar orbit is extending northward over the next 4 days to face maximum declination of ∠18.817° at the point of next northern standstill on 23 January 2089 at 16:28 in ♊ Gemini.

Draconic month

14 days since the beginning of this draconic month in ♎ Libra the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 6 days

In 6 days on 26 January 2089 at 11:25 in ♌ Leo 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.
