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 9 August 2046 at 01:15 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 ∠23° of ♏ Scorpio tropical zodiac sector.

Sturgeon Moon after 7 days

Next Full Moon is the Sturgeon Moon of August 2046 after 7 days on 16 August 2046 at 14:50.

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 ∠1932"

Lunar disc appears visually 2% wider than solar disc. Moon and Sun apparent angular diameters are ∠1932" and ∠1893".

Lunation 576 / 1529

The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 576 of Meeus index or 1529 from Brown series.

Synodic month length 29.33 days

The length of this lunation is 29 days, 8 hours and 1 minute and it is longer than the upcoming lunation's length. This is the year's shortest synodic month of 2046. 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 4 hours and 44 minutes shorter than the mean synodic month length. It is 1 hour and 25 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠328°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠328° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠345.8°.

Moon after perigee

5 days since point of perigee on 4 August 2046 at 09:16 in ♍ Virgo the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 10 days until the Moon reaches the point of next apogee on 20 August 2046 at 01:53 in ♈ Aries.

Distance to Moon 371 050 km

The Moon is 371 050 km (230 560 mi) away from Earth and getting further over the next 10 days until the point apogee when Earth-Moon distance is going to be 405 828 km (252 170 mi).

Moon before ascending node

7 days after descending node on 2 August 2046 at 00:47 in ♌ Leo 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 15 August 2046 at 00:43 in ♒ Aquarius.

Moon before southern standstill

10 days since the last northern standstill on 29 July 2046 at 22:44 in ♊ Gemini when the Moon has reached North declination of ∠26.730° the lunar orbit is extending southward over the next 2 days to face maximum declination of ∠-26.723° at the point of next southern standstill on 11 August 2046 at 15:06 in ♐ Sagittarius.

Draconic month

21 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 16 August 2046 at 14:50 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.
