First Quarter in Sagittarius

First Quarter on . The illuminated surface of the moon is 56% and growing larger. The lunar cycle is 8 days young.

* The exact date and time of this First Quarter phase is on 4 September 2068 at 22:04 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 ∠21° of ♐ Sagittarius tropical zodiac sector.

Harvest Moon after 6 days

Next Full Moon is the Harvest Moon of September 2068 after 6 days on 11 September 2068 at 17:19.

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 ∠1858"

Lunar disc appears visually 2.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1858" and ∠1904".

Lunation 849 / 1802

The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 849 of Meeus index or 1802 from Brown series.

Synodic month length 29.68 days

The length of this lunation is 29 days, 16 hours and 20 minutes and it is 1 hour and 9 minutes shorter 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 3 hours and 36 minutes longer than the mean synodic month length. It is 3 hours and 27 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠160.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠160.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠183.9°.

Moon before perigee

6 days since point of apogee on 29 August 2068 at 20:38 in ♍ Virgo the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 6 days until the Moon reaches the point of next perigee on 12 September 2068 at 00:17 in ♈ Aries.

Distance to Moon 385 681 km

The Moon is 385 681 km (239 651 mi) away from Earth and getting closer over the next 6 days until the point perigee when Earth-Moon distance is going to be 356 950 km (221 798 mi).

Moon after ascending node

1 day after ascending node on 3 September 2068 at 12:48 in ♏ Scorpio 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 16 September 2068 at 02:30 in ♉ Taurus.

Moon at southern standstill

At 09:10 the Moon is meeting its standstill point to reach South declination of ∠-20.990°. Over the upcoming 12 days the lunar orbit is going to tilt northward to face maximum declination of ∠20.889° at the point of next northern standstill in ♊ Gemini on 17 September 2068 at 21:08.

Draconic month

1 day since the beginning of this draconic month in ♏ Scorpio the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 6 days

In 6 days on 11 September 2068 at 17:19 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.
