First Quarter in Libra

First Quarter on . Illuminated surface of the Moon is 63% and growing larger. Lunar cycle is 8 days young.

* The exact date and time of this First Quarter phase is on 28 June 2020 at 08:16 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 ∠24° of ♎ Libra tropical zodiac sector.

Buck Moon after 5 days

Next Full Moon is the Buck Moon of July 2020 after 5 days on 5 July 2020 at 04:44.

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 ∠1972"

Lunar disc appears visually 4.4% wider than solar disc. Moon and Sun apparent angular diameters are ∠1972" and ∠1887".

Lunation 253 / 1206

The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 253 of Meeus index or 1206 from Brown series.

Synodic month length 29.45 days

The length of this lunation is 29 days, 10 hours and 52 minutes and it is 1 hour and 43 minutes longer 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 shorter than mean

The length of the current synodic month is 1 hour and 53 minutes shorter than the mean synodic month length. It is 4 hours and 17 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠263.8°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠263.8° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠296.9°.

Moon before perigee

14 days since point of apogee on 15 June 2020 at 00:56 in ♈ Aries the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next day until the Moon reaches the point of next perigee on 30 June 2020 at 02:09 in ♏ Scorpio.

Distance to Moon 363 419 km

The Moon is 363 419 km (225 818 mi) away from Earth and getting closer over the next day until the point perigee when Earth-Moon distance is going to be 368 958 km (229 260 mi).

Moon before descending node

8 days after ascending node on 21 June 2020 at 04:24 in ♊ Gemini the Moon is positioned north of the ecliptic over the following 4 days until the lunar crosses the ecliptic again from North to South in descending node on 4 July 2020 at 03:18 in ♐ Sagittarius.

Moon before southern standstill

7 days since the last northern standstill on 22 June 2020 at 03:56 in ♋ Cancer when the Moon has reached North declination of ∠24.070° the lunar orbit is extending southward over the next 5 days to face maximum declination of ∠-24.064° at the point of next southern standstill on 5 July 2020 at 01:37 in ♑ Capricorn.

Draconic month

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

Syzygy in 5 days

In 5 days on 5 July 2020 at 04:44 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.
