First Quarter in Libra

First Quarter on . Illuminated surface of the Moon is 49% and growing larger. Lunar cycle is 7 days young.

* The exact date and time of this First Quarter phase is on 14 July 2005 at 15:20 UTC.

Moonrise and moonset

Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon in ♎ Libra

Moon is passing about ∠21° of ♎ Libra tropical zodiac sector.

Buck Moon after 6 days

Next Full Moon is the Buck Moon of July 2005 after 6 days on 21 July 2005 at 11:00.

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 ∠1839"

Lunar disc appears visually 2.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1839" and ∠1888".

Lunation 68 / 1021

The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 68 of Meeus index or 1021 from Brown series.

Synodic month length 29.63 days

The length of this lunation is 29 days, 15 hours and 2 minutes and it is 39 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 2 hours and 18 minutes longer than the mean synodic month length. It is 4 hours and 45 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠158.8°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠158.8° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠181.9°.

Moon after apogee

5 days since point of apogee on 8 July 2005 at 17:39 in ♌ Leo the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 7 days until the Moon reaches the point of next perigee on 21 July 2005 at 19:44 in ♑ Capricorn.

Distance to Moon 389 832 km

The Moon is 389 832 km (242 230 mi) away from Earth and getting closer over the next 7 days until the point perigee when Earth-Moon distance is going to be 357 160 km (221 929 mi).

Moon in descending node

Moon is in descending node in ♎ Libra at 06:35 crossing the ecliptic from North to South. Lunar position remains south of if for the upcoming 12 days until Moon's next ascending node later on 26 July 2005 at 17:58 in ♈ Aries.

Moon before southern standstill

8 days since the last northern standstill on 5 July 2005 at 13:08 in ♊ Gemini when the Moon has reached North declination of ∠28.208° the lunar orbit is extending southward over the next 5 days to face maximum declination of ∠-28.265° at the point of next southern standstill on 19 July 2005 at 17:52 in ♐ Sagittarius.

Draconic month

14 days since the beginning of this draconic month in ♈ Aries the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 6 days

In 6 days on 21 July 2005 at 11:00 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.
