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 29 January 2080 at 21:37 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 ∠18° of ♉ Taurus tropical zodiac sector.

Snow Moon after 6 days

Next Full Moon is the Snow Moon of February 2080 after 6 days on 5 February 2080 at 12:21.

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 ∠1932"

Lunar disc appears visually 0.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1932" and ∠1948".

Lunation 990 / 1943

The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 990 of Meeus index or 1943 from Brown series.

Synodic month length 29.76 days

The length of this lunation is 29 days, 18 hours and 16 minutes and it is 2 hours and 21 minutes longer than the upcoming lunation's length. This is the year's longest synodic month of 2080. 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 32 minutes longer than the mean synodic month length. It is 1 hour and 31 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠199.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠199.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠228.8°.

Moon before perigee

10 days since point of apogee on 19 January 2080 at 22:45 in ♑ Capricorn 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 4 February 2080 at 07:30 in ♋ Cancer.

Distance to Moon 371 061 km

The Moon is 371 061 km (230 567 mi) away from Earth and getting closer over the next 4 days until the point perigee when Earth-Moon distance is going to be 359 104 km (223 137 mi).

Moon after ascending node

2 days after ascending node on 28 January 2080 at 00:20 in ♈ Aries the Moon is positioned north of the ecliptic over the following 10 days until the lunar crosses the ecliptic again from North to South in descending node on 9 February 2080 at 12:47 in ♎ Libra.

Moon before northern standstill

10 days since the last southern standstill on 19 January 2080 at 15:20 in ♐ Sagittarius when the Moon has reached South declination of ∠-28.251° the lunar orbit is extending northward over the next 3 days to face maximum declination of ∠28.345° at the point of next northern standstill on 2 February 2080 at 14:34 in ♊ Gemini.

Draconic month

2 days since the beginning of this draconic month in ♈ Aries the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 6 days

In 6 days on 5 February 2080 at 12:21 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.
