First Quarter in Taurus

First Quarter on . The illuminated surface of the moon is 57% and growing larger. The lunar cycle is 8 days young.

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

Moon is passing about ∠9° of ♉ Taurus tropical zodiac sector.

Wolf Moon after 5 days

Next Full Moon is the Wolf Moon of January 2089 after 5 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 ∠1910"

Lunar disc appears visually 2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1910" and ∠1950".

Lunation 1101 / 2054

The Moon is 8 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

9 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 5 days until the Moon reaches the point of next perigee on 25 January 2089 at 19:36 in ♋ Cancer.

Distance to Moon 375 194 km

The Moon is 375 194 km (233 135 mi) away from Earth and getting closer over the next 5 days until the point perigee when Earth-Moon distance is going to be 357 298 km (222 015 mi).

Moon after descending node

1 day after descending node on 19 January 2089 at 04:30 in ♈ Aries the Moon is positioned south of the ecliptic over the following 11 days until the lunar crosses the ecliptic again from South to North in ascending node on 31 January 2089 at 14:33 in ♎ Libra.

Moon before northern standstill

11 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 3 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

15 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 5 days

In 5 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.
