First Quarter in Scorpio

First Quarter on . The illuminated surface of the moon is 45% and growing larger. The lunar cycle is 7 days young.

* The exact date and time of this First Quarter phase is on 29 July 2047 at 22:03 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 is entering ♏ Scorpio

Moon is passing first ∠1° of ♏ Scorpio tropical zodiac sector.

Sturgeon Moon after 7 days

Next Full Moon is the Sturgeon Moon of August 2047 after 7 days on 5 August 2047 at 20:38.

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 ∠1972"

Lunar disc appears visually 4.2% wider than solar disc. Moon and Sun apparent angular diameters are ∠1972" and ∠1890".

Lunation 588 / 1541

The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 588 of Meeus index or 1541 from Brown series.

Synodic month length 29.44 days

The length of this lunation is 29 days, 10 hours and 27 minutes and it is 1 hour and 12 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 shorter than mean

The length of the current synodic month is 2 hours and 17 minutes shorter than the mean synodic month length. It is 3 hours and 52 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠274.9°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠274.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠306.1°.

Moon before perigee

13 days since point of apogee on 16 July 2047 at 03:57 in ♉ Taurus the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next day until the Moon reaches the point of next perigee on 30 July 2047 at 09:01 in ♏ Scorpio.

Distance to Moon 363 494 km

The Moon is 363 494 km (225 865 mi) away from Earth and getting closer over the next day until the point perigee when Earth-Moon distance is going to be 369 644 km (229 686 mi).

Moon before ascending node

7 days after descending node on 21 July 2047 at 20:52 in ♋ Cancer the Moon is positioned south of the ecliptic over the following 5 days until the lunar crosses the ecliptic again from South to North in ascending node on 3 August 2047 at 19:59 in ♑ Capricorn.

Moon before southern standstill

9 days since the last northern standstill on 19 July 2047 at 18:19 in ♊ Gemini when the Moon has reached North declination of ∠25.339° the lunar orbit is extending southward over the next 3 days to face maximum declination of ∠-25.317° at the point of next southern standstill on 1 August 2047 at 22:27 in ♐ Sagittarius.

Draconic month

22 days since the beginning of this draconic month in ♑ Capricorn the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 7 days

In 7 days on 5 August 2047 at 20:38 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.
