First Quarter in Scorpio

First Quarter on . Illuminated surface of the Moon is 55% and growing larger. Lunar cycle is 8 days young.

* The exact date and time of this First Quarter phase is on 30 July 2066 at 02:01 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 ∠13° of ♏ Scorpio tropical zodiac sector.

Sturgeon Moon after 6 days

Next Full Moon is the Sturgeon Moon of August 2066 after 6 days on 5 August 2066 at 16:59.

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 ∠1938"

Lunar disc appears visually 2.5% wider than solar disc. Moon and Sun apparent angular diameters are ∠1938" and ∠1890".

Lunation 823 / 1776

The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 823 of Meeus index or 1776 from Brown series.

Synodic month length 29.59 days

The length of this lunation is 29 days, 14 hours and 16 minutes and it is 1 hour and 18 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 1 hour and 32 minutes longer than the mean synodic month length. It is 5 hours and 31 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠207°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠207° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠236.4°.

Moon before perigee

10 days since point of apogee on 19 July 2066 at 16:13 in ♊ Gemini the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 4 days until the Moon reaches the point of next perigee on 4 August 2066 at 03:18 in ♑ Capricorn.

Distance to Moon 369 905 km

The Moon is 369 905 km (229 848 mi) away from Earth and getting closer over the next 4 days until the point perigee when Earth-Moon distance is going to be 360 710 km (224 135 mi).

Moon before ascending node

9 days after descending node on 20 July 2066 at 16:05 in ♋ Cancer the Moon is positioned south of the ecliptic over the following 3 days until the lunar crosses the ecliptic again from South to North in ascending node on 3 August 2066 at 08:34 in ♑ Capricorn.

Moon before southern standstill

11 days since the last northern standstill on 18 July 2066 at 23:31 in ♊ Gemini when the Moon has reached North declination of ∠24.725° the lunar orbit is extending southward over the next 2 days to face maximum declination of ∠-24.680° at the point of next southern standstill on 2 August 2066 at 00:55 in ♐ Sagittarius.

Draconic month

23 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 6 days

In 6 days on 5 August 2066 at 16:59 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.
