First Quarter in Pisces

First Quarter on . Illuminated surface of the Moon is 51% and growing larger. Lunar cycle is 7 days young.

* The exact date and time of this First Quarter phase is on 7 December 2016 at 09:03 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 passing about ∠17° of ♓ Pisces tropical zodiac sector.

Cold Moon after 6 days

Next Full Moon is the Cold Moon of December 2016 after 6 days on 14 December 2016 at 00:06.

Neap tide

There is low ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at big angle, so their combined tidal force is weak.

Apparent angular diameter ∠1915"

Lunar disc appears visually 1.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1915" and ∠1948".

Lunation 209 / 1162

The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 209 of Meeus index or 1162 from Brown series.

Synodic month length 29.77 days

The length of this lunation is 29 days, 18 hours and 35 minutes and it is 1 hour and 21 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 5 hours and 51 minutes longer than the mean synodic month length. It is 1 hour and 12 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠194.9°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠194.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠223.4°.

Moon before perigee

9 days since point of apogee on 27 November 2016 at 20:08 in ♏ Scorpio 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 12 December 2016 at 23:27 in ♉ Taurus.

Distance to Moon 374 375 km

The Moon is 374 375 km (232 626 mi) away from Earth and getting closer over the next 5 days until the point perigee when Earth-Moon distance is going to be 358 463 km (222 739 mi).

Moon after descending node

1 day after descending node on 6 December 2016 at 17:35 in ♓ Pisces 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 19 December 2016 at 04:46 in ♍ Virgo.

Moon after southern standstill

5 days since the last southern standstill on 1 December 2016 at 19:56 in ♐ Sagittarius when the Moon has reached South declination of ∠-18.908° the lunar orbit is extending northward over the next 7 days to face maximum declination of ∠18.937° at the point of next northern standstill on 14 December 2016 at 21:43 in ♊ Gemini.

Draconic month

15 days since the beginning of this draconic month in ♍ Virgo the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 6 days

In 6 days on 14 December 2016 at 00:06 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.
