First Quarter in Sagittarius

First Quarter on . The illuminated surface of the moon is 59% and growing larger. The lunar cycle is 8 days young.

* The exact date and time of this First Quarter phase is on 17 August 2086 at 14:14 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 ♐ Sagittarius

Moon is passing about ∠6° of ♐ Sagittarius tropical zodiac sector.

Sturgeon Moon after 6 days

Next Full Moon is the Sturgeon Moon of August 2086 after 6 days on 24 August 2086 at 17:25.

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 ∠1817"

Lunar disc appears visually 4.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1817" and ∠1896".

Lunation 1071 / 2024

The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 1071 of Meeus index or 2024 from Brown series.

Synodic month length 29.61 days

The length of this lunation is 29 days, 14 hours and 39 minutes and it is 2 hours 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 1 hour and 55 minutes longer than the mean synodic month length. It is 5 hours and 8 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠129.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠129.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠157.5°.

Moon after apogee

4 days since point of apogee on 13 August 2086 at 21:28 in ♎ Libra the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 7 days until the Moon reaches the point of next perigee on 26 August 2086 at 02:04 in ♓ Pisces.

Distance to Moon 394 572 km

The Moon is 394 572 km (245 176 mi) away from Earth and getting closer over the next 7 days until the point perigee when Earth-Moon distance is going to be 359 804 km (223 572 mi).

Moon in ascending node

Moon is in ascending node in ♐ Sagittarius at 19:24 crossing the ecliptic from South to North. Lunar position remains north of if for the upcoming 12 days until Moon's next descending node later on 31 August 2086 at 08:57 in ♊ Gemini.

Moon before southern standstill

13 days since the last northern standstill on 4 August 2086 at 20:25 in ♊ Gemini when the Moon has reached North declination of ∠22.322° the lunar orbit is extending southward over the next day to face maximum declination of ∠-22.198° at the point of next southern standstill on 19 August 2086 at 11:08 in ♐ Sagittarius.

New draconic month

At 19:24 in the point ot ascending node the Moon is completing the last draconic month and is entering a new one while the lunar orbit is crossing the ecliptic from South to North.

Syzygy in 6 days

In 6 days on 24 August 2086 at 17:25 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.
