First Quarter in Sagittarius

First Quarter on . The illuminated surface of the moon is 51% and growing larger. The lunar cycle is 7 days young.

* The exact date and time of this First Quarter phase is on 2 September 2014 at 11:11 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 ∠10° of ♐ Sagittarius tropical zodiac sector.

Harvest Moon after 6 days

Next Full Moon is the Harvest Moon of September 2014 after 6 days on 9 September 2014 at 01:38.

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 ∠1907"

Lunar disc appears visually 0.2% wider than solar disc. Moon and Sun apparent angular diameters are ∠1907" and ∠1902".

Lunation 181 / 1134

The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 181 of Meeus index or 1134 from Brown series.

Synodic month length 29.67 days

The length of this lunation is 29 days, 16 hours and 1 minute and it is 18 minutes longer than the upcoming lunation's length. This is the year's longest synodic month of 2014. 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 17 minutes longer than the mean synodic month length. It is 3 hours and 46 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠192.1°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠192.1° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠218.3°.

Moon before perigee

9 days since point of apogee on 24 August 2014 at 06:09 in ♌ Leo the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 5 days until the Moon reaches the point of next perigee on 8 September 2014 at 03:29 in ♓ Pisces.

Distance to Moon 375 917 km

The Moon is 375 917 km (233 584 mi) away from Earth and getting closer over the next 5 days until the point perigee when Earth-Moon distance is going to be 358 388 km (222 692 mi).

Moon after ascending node

3 days after ascending node on 29 August 2014 at 13:14 in ♎ Libra the Moon is positioned north of the ecliptic over the following 8 days until the lunar crosses the ecliptic again from North to South in descending node on 11 September 2014 at 07:32 in ♈ Aries.

Moon before southern standstill

13 days since the last northern standstill on 19 August 2014 at 22:12 in ♊ Gemini when the Moon has reached North declination of ∠18.750° the lunar orbit is extending southward over the next day to face maximum declination of ∠-18.641° at the point of next southern standstill on 3 September 2014 at 13:10 in ♐ Sagittarius.

Draconic month

3 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 6 days

In 6 days on 9 September 2014 at 01:38 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.
