First Quarter in Scorpio

First Quarter on . The illuminated surface of the moon is 56% and growing larger. The lunar cycle is 8 days young.

* The exact date and time of this First Quarter phase is on 2 August 2071 at 21:04 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 ∠19° of ♏ Scorpio tropical zodiac sector.

Sturgeon Moon after 7 days

Next Full Moon is the Sturgeon Moon of August 2071 after 7 days on 10 August 2071 at 23:39.

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 ∠1830"

Lunar disc appears visually 3.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1830" and ∠1891".

Lunation 885 / 1838

The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 885 of Meeus index or 1838 from Brown series.

Synodic month length 29.31 days

The length of this lunation is 29 days, 7 hours and 20 minutes and it is 1 hour and 45 minutes shorter 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 5 hours and 24 minutes shorter than the mean synodic month length. It is 45 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠5.3°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠5.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠21.2°.

Moon before apogee

7 days since point of perigee on 26 July 2071 at 17:22 in ♋ Cancer the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 5 days until the Moon reaches the point of next apogee on 8 August 2071 at 20:04 in ♑ Capricorn.

Distance to Moon 391 589 km

The Moon is 391 589 km (243 322 mi) away from Earth and getting further over the next 5 days until the point apogee when Earth-Moon distance is going to be 406 136 km (252 361 mi).

Moon after ascending node

3 days after ascending node on 30 July 2071 at 18:19 in ♍ Virgo 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 14 August 2071 at 06:42 in ♓ Pisces.

Moon before southern standstill

9 days since the last northern standstill on 24 July 2071 at 19:33 in ♊ Gemini when the Moon has reached North declination of ∠18.332° the lunar orbit is extending southward over the next 3 days to face maximum declination of ∠-18.284° at the point of next southern standstill on 6 August 2071 at 22:51 in ♐ Sagittarius.

Draconic month

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

Syzygy in 7 days

In 7 days on 10 August 2071 at 23:39 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.
