First Quarter in Sagittarius

First Quarter on . The illuminated surface of the moon is 52% and growing larger. The lunar cycle is 7 days young.

* The exact date and time of this First Quarter phase is on 22 August 2080 at 07:07 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 ♐ Sagittarius

Moon is passing first ∠3° of ♐ Sagittarius tropical zodiac sector.

Sturgeon Moon after 7 days

Next Full Moon is the Sturgeon Moon of August 2080 after 7 days on 30 August 2080 at 10:41.

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 ∠1821"

Lunar disc appears visually 4.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1821" and ∠1898".

Lunation 997 / 1950

The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 997 of Meeus index or 1950 from Brown series.

Synodic month length 29.34 days

The length of this lunation is 29 days, 8 hours and 11 minutes and it is 2 hours and 8 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 4 hours and 33 minutes shorter than the mean synodic month length. It is 1 hour and 36 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠12°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠12° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠29.1°.

Moon before apogee

7 days since point of perigee on 14 August 2080 at 15:04 in ♌ Leo the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 4 days until the Moon reaches the point of next apogee on 27 August 2080 at 06:54 in ♒ Aquarius.

Distance to Moon 393 576 km

The Moon is 393 576 km (244 557 mi) away from Earth and getting further over the next 4 days until the point apogee when Earth-Moon distance is going to be 405 834 km (252 174 mi).

Moon after descending node

4 days after descending node on 18 August 2080 at 02:15 in ♎ Libra the Moon is positioned south of the ecliptic over the following 10 days until the lunar crosses the ecliptic again from South to North in ascending node on 1 September 2080 at 13:10 in ♓ Pisces.

Moon before southern standstill

10 days since the last northern standstill on 11 August 2080 at 20:32 in ♊ Gemini when the Moon has reached North declination of ∠28.549° the lunar orbit is extending southward over the next 2 days to face maximum declination of ∠-28.609° at the point of next southern standstill on 24 August 2080 at 19:26 in ♐ Sagittarius.

Draconic month

17 days since the beginning of this draconic month in ♈ Aries the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 7 days

In 7 days on 30 August 2080 at 10:41 in ♓ Pisces 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.
