First Quarter in Taurus

First Quarter on . Illuminated surface of the Moon is 50% and growing larger. Lunar cycle is 7 days young.

* The exact date and time of this First Quarter phase is on 23 January 2094 at 11:34 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 is entering ♉ Taurus

Moon is passing first ∠4° of ♉ Taurus tropical zodiac sector.

Wolf Moon after 8 days

Next Full Moon is the Wolf Moon of January 2094 after 8 days on 31 January 2094 at 12:36.

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 ∠1883"

Lunar disc appears visually 3.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1883" and ∠1949".

Lunation 1163 / 2116

The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 1163 of Meeus index or 2116 from Brown series.

Synodic month length 29.44 days

The length of this lunation is 29 days, 10 hours and 38 minutes and it is 37 minutes longer 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 shorter than mean

The length of the current synodic month is 2 hours and 6 minutes shorter than the mean synodic month length. It is 4 hours and 3 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠352.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠352.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠7.9°.

Moon after perigee

6 days since point of perigee on 17 January 2094 at 05:33 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 7 days until the Moon reaches the point of next apogee on 31 January 2094 at 11:51 in ♌ Leo.

Distance to Moon 380 711 km

The Moon is 380 711 km (236 563 mi) away from Earth and getting further over the next 7 days until the point apogee when Earth-Moon distance is going to be 406 394 km (252 522 mi).

Moon before ascending node

7 days after descending node on 16 January 2094 at 02:40 in ♑ Capricorn the Moon is positioned south of the ecliptic over the following 5 days until the lunar crosses the ecliptic again from South to North in ascending node on 29 January 2094 at 09:03 in ♋ Cancer.

Moon before northern standstill

7 days since the last southern standstill on 15 January 2094 at 19:36 in ♑ Capricorn when the Moon has reached South declination of ∠-22.474° the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠22.474° at the point of next northern standstill on 28 January 2094 at 23:58 in ♋ Cancer.

Draconic month

21 days since the beginning of this draconic month in ♋ Cancer the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 8 days

In 8 days on 31 January 2094 at 12:36 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.
