First Quarter in Scorpio

First Quarter on . The illuminated surface of the moon is 55% and growing larger. The lunar cycle is 8 days young.

* The exact date and time of this First Quarter phase is on 8 August 2057 at 01:30 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 ♏ Scorpio

Moon is passing about ∠22° of ♏ Scorpio tropical zodiac sector.

Sturgeon Moon after 6 days

Next Full Moon is the Sturgeon Moon of August 2057 after 6 days on 14 August 2057 at 17:21.

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 ∠1955"

Lunar disc appears visually 3.2% wider than solar disc. Moon and Sun apparent angular diameters are ∠1955" and ∠1893".

Lunation 712 / 1665

The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 712 of Meeus index or 1665 from Brown series.

Synodic month length 29.56 days

The length of this lunation is 29 days, 13 hours and 23 minutes and it is 1 hour and 17 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 39 minutes longer than the mean synodic month length. It is 6 hours and 24 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠222.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠222.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠255.9°.

Moon before perigee

11 days since point of apogee on 27 July 2057 at 15:44 in ♊ Gemini the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 3 days until the Moon reaches the point of next perigee on 12 August 2057 at 10:32 in ♑ Capricorn.

Distance to Moon 366 673 km

The Moon is 366 673 km (227 840 mi) away from Earth and getting closer over the next 3 days until the point perigee when Earth-Moon distance is going to be 363 290 km (225 738 mi).

Moon before descending node

10 days after ascending node on 28 July 2057 at 14:55 in ♊ Gemini the Moon is positioned north of the ecliptic over the following 2 days until the lunar crosses the ecliptic again from North to South in descending node on 11 August 2057 at 07:29 in ♑ Capricorn.

Moon before southern standstill

10 days since the last northern standstill on 29 July 2057 at 08:55 in ♋ Cancer when the Moon has reached North declination of ∠23.709° the lunar orbit is extending southward over the next 3 days to face maximum declination of ∠-23.760° at the point of next southern standstill on 11 August 2057 at 22:52 in ♑ Capricorn.

Draconic month

10 days since the beginning of this draconic month in ♊ Gemini the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 6 days

In 6 days on 14 August 2057 at 17:21 in ♒ Aquarius 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.
