First Quarter in Scorpio

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 3 August 2033 at 10:26 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 ♏ Scorpio

Moon is passing about ∠12° of ♏ Scorpio tropical zodiac sector.

Sturgeon Moon after 7 days

Next Full Moon is the Sturgeon Moon of August 2033 after 7 days on 10 August 2033 at 18:08.

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 ∠1783"

Lunar disc appears visually 5.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1783" and ∠1891".

Lunation 415 / 1368

The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 415 of Meeus index or 1368 from Brown series.

Synodic month length 29.56 days

The length of this lunation is 29 days, 13 hours and 27 minutes and it is 2 hours and 33 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 longer than mean

The length of the current synodic month is 43 minutes longer than the mean synodic month length. It is 6 hours and 20 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠108.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠108.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠140.6°.

Moon after apogee

2 days since point of apogee on 31 July 2033 at 23:13 in ♎ Libra the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 9 days until the Moon reaches the point of next perigee on 12 August 2033 at 21:22 in ♓ Pisces.

Distance to Moon 401 892 km

The Moon is 401 892 km (249 724 mi) away from Earth and getting closer over the next 9 days until the point perigee when Earth-Moon distance is going to be 362 710 km (225 378 mi).

Moon after ascending node

2 days after ascending node on 1 August 2033 at 03:38 in ♎ Libra 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 2033 at 11:54 in ♈ Aries.

Moon before southern standstill

11 days since the last northern standstill on 23 July 2033 at 11:24 in ♊ Gemini when the Moon has reached North declination of ∠18.624° the lunar orbit is extending southward over the next 3 days to face maximum declination of ∠-18.529° at the point of next southern standstill on 7 August 2033 at 00:25 in ♑ Capricorn.

Draconic month

2 days since the beginning of this draconic month in ♎ Libra 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 2033 at 18:08 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.
