First Quarter in Libra

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 22 June 2007 at 13:15 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 passing about ∠12° of ♎ Libra tropical zodiac sector.

Strawberry Moon after 7 days

Next Full Moon is the Strawberry Moon of June 2007 after 7 days on 30 June 2007 at 13:49.

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 ∠1771"

Lunar disc appears visually 6.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1771" and ∠1888".

Lunation 92 / 1045

The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 92 of Meeus index or 1045 from Brown series.

Synodic month length 29.37 days

The length of this lunation is 29 days, 8 hours and 51 minutes and it is 2 hours and 8 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 shorter than mean

The length of the current synodic month is 3 hours and 53 minutes shorter than the mean synodic month length. It is 2 hours and 16 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠38.7°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠38.7° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠64.2°.

Moon before apogee

10 days since point of perigee on 12 June 2007 at 17:07 in ♉ Taurus the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next day until the Moon reaches the point of next apogee on 24 June 2007 at 14:25 in ♎ Libra.

Distance to Moon 404 686 km

The Moon is 404 686 km (251 460 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 404 540 km (251 370 mi).

Moon after descending node

2 days after descending node on 20 June 2007 at 19:32 in ♍ Virgo the Moon is positioned south of the ecliptic over the following 11 days until the lunar crosses the ecliptic again from South to North in ascending node on 5 July 2007 at 01:39 in ♓ Pisces.

Moon before southern standstill

8 days since the last northern standstill on 15 June 2007 at 08:31 in ♊ Gemini when the Moon has reached North declination of ∠28.212° the lunar orbit is extending southward over the next 6 days to face maximum declination of ∠-28.215° at the point of next southern standstill on 29 June 2007 at 15:41 in ♐ Sagittarius.

Draconic month

15 days since the beginning of this draconic month in ♓ Pisces the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 7 days

In 7 days on 30 June 2007 at 13:49 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.
