First Quarter in Libra

First Quarter on . The illuminated surface of the moon is 48% and growing larger. The lunar cycle is 7 days young.

* The exact date and time of this First Quarter phase is on 20 July 2094 at 17:25 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 ♎ Libra

Moon is leaving the last ∠4° of ♎ Libra tropical zodiac sector and will enter ♏ Scorpio later.

Buck Moon after 7 days

Next Full Moon is the Buck Moon of July 2094 after 7 days on 27 July 2094 at 17:39.

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 ∠1811"

Lunar disc appears visually 4.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1811" and ∠1888".

Lunation 1169 / 2122

The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 1169 of Meeus index or 2122 from Brown series.

Synodic month length 29.63 days

The length of this lunation is 29 days, 15 hours and 1 minute and it is 55 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 16 minutes longer than the mean synodic month length. It is 4 hours and 47 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠141.9°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠141.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠167.4°.

Moon after apogee

4 days since point of apogee on 16 July 2094 at 04:45 in ♍ Virgo 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 28 July 2094 at 16:14 in ♒ Aquarius.

Distance to Moon 395 683 km

The Moon is 395 683 km (245 866 mi) away from Earth and getting closer over the next 8 days until the point perigee when Earth-Moon distance is going to be 358 501 km (222 762 mi).

Moon before descending node

9 days after ascending node on 11 July 2094 at 11:47 in ♋ Cancer 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 25 July 2094 at 20:41 in ♑ Capricorn.

Moon before southern standstill

8 days since the last northern standstill on 11 July 2094 at 20:37 in ♋ Cancer when the Moon has reached North declination of ∠23.299° the lunar orbit is extending southward over the next 5 days to face maximum declination of ∠-23.317° at the point of next southern standstill on 26 July 2094 at 04:07 in ♑ Capricorn.

Draconic month

9 days since the beginning of this draconic month in ♋ Cancer the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 7 days

In 7 days on 27 July 2094 at 17:39 in ♑ Capricorn 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.
