First Quarter in Pisces

First Quarter on . Illuminated surface of the Moon is 56% and growing larger. Lunar cycle is 8 days young.

* The exact date and time of this First Quarter phase is on 11 December 2051 at 00:07 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 ♓ Pisces

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

Cold Moon after 6 days

Next Full Moon is the Cold Moon of December 2051 after 6 days on 17 December 2051 at 16:05.

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 ∠1948"

Lunar disc appears visually 0% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1948" and ∠1949".

Lunation 642 / 1595

The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 642 of Meeus index or 1595 from Brown series.

Synodic month length 29.73 days

The length of this lunation is 29 days, 17 hours and 29 minutes and it is 2 hours and 4 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 longer than mean

The length of the current synodic month is 4 hours and 45 minutes longer than the mean synodic month length. It is 2 hours and 18 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠214.3°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠214.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠248.4°.

Moon before perigee

11 days since point of apogee on 29 November 2051 at 23:42 in ♎ Libra 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 15 December 2051 at 19:57 in ♉ Taurus.

Distance to Moon 367 919 km

The Moon is 367 919 km (228 614 mi) away from Earth and getting closer over the next 4 days until the point perigee when Earth-Moon distance is going to be 361 745 km (224 778 mi).

Moon before descending node

12 days after ascending node on 29 November 2051 at 08:08 in ♎ Libra the Moon is positioned north of the ecliptic over the following day until the lunar crosses the ecliptic again from North to South in descending node on 13 December 2051 at 08:09 in ♈ Aries.

Moon before northern standstill

7 days since the last southern standstill on 4 December 2051 at 11:27 in ♐ Sagittarius when the Moon has reached South declination of ∠-18.781° the lunar orbit is extending northward over the next 6 days to face maximum declination of ∠18.789° at the point of next northern standstill on 17 December 2051 at 14:21 in ♊ Gemini.

Draconic month

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

Syzygy in 6 days

In 6 days on 17 December 2051 at 16:05 in ♊ Gemini 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.
