First Quarter in Sagittarius

First Quarter on . The illuminated surface of the moon is 60% and growing larger. The lunar cycle is 8 days young.

* The exact date and time of this First Quarter phase is on 9 September 2016 at 11:49 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 ∠0° of ♐ Sagittarius tropical zodiac sector.

Harvest Moon after 6 days

Next Full Moon is the Harvest Moon of September 2016 after 6 days on 16 September 2016 at 19:05.

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 ∠1801"

Lunar disc appears visually 5.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1801" and ∠1906".

Lunation 206 / 1159

The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 206 of Meeus index or 1159 from Brown series.

Synodic month length 29.63 days

The length of this lunation is 29 days, 15 hours and 8 minutes and it is 2 hours and 19 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 longer than mean

The length of the current synodic month is 2 hours and 24 minutes longer than the mean synodic month length. It is 4 hours and 39 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠112.8°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠112.8° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠144.6°.

Moon after apogee

3 days since point of apogee on 6 September 2016 at 18:44 in ♏ Scorpio the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 8 days until the Moon reaches the point of next perigee on 18 September 2016 at 17:00 in ♈ Aries.

Distance to Moon 398 051 km

The Moon is 398 051 km (247 337 mi) away from Earth and getting closer over the next 8 days until the point perigee when Earth-Moon distance is going to be 361 894 km (224 871 mi).

Moon before descending node

8 days after ascending node on 1 September 2016 at 15:27 in ♍ Virgo the Moon is positioned north of the ecliptic over the following 5 days until the lunar crosses the ecliptic again from North to South in descending node on 15 September 2016 at 23:55 in ♓ Pisces.

Moon at southern standstill

At 22:05 the Moon is meeting its standstill point to reach South declination of ∠-18.451°. Over the upcoming 13 days the lunar orbit is going to tilt northward to face maximum declination of ∠18.475° at the point of next northern standstill in ♊ Gemini on 23 September 2016 at 16:44.

Draconic month

8 days since the beginning of this draconic month in ♍ Virgo the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 6 days

In 6 days on 16 September 2016 at 19:05 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.
